A 5-Month-Old Baby’s Developmental Milestones

We have divided these developmental milestones to three categories and will see the key formative landmarks under each category.

Cognitive Developmental Milestones

The baby still shows preference for bold and solid colors.

These 5-month milestones pertain to intelligence, language, thinking, and decision-making capabilities.

  1. More keen and discerning: Your baby is now keen on watching objects and people around him as they captivate him. As he gets a sense of reflection, he will be prone to smiling and giggling when called upon and on funny noises (1). He is more alert than ever and shows an increase in his level of curiosity.

Referring to her youngest daughter’s milestones, Amber Massey, a mother of three girls, notes, “I’ve noticed her face lights up when Jordan (her father), or I enter the room or her line of sight- and she especially loves her sisters. She is still a social little girl and wants to be in the mix of everything all the time- so when we leave she is noticeably upset, depending on what she’s doing or her mood (i).”

  1. Gets distracted easily: As he has a penchant for looking at new objects, distracting your baby would be easy. Walking towards him with a new toy or object in front of him, and he stops whatever he is doing to look at the fascinating new thing.
  1. Attracted to colorful objects: The baby still shows preference for bold and solid colors (2). This is an indicator of a better eye and brain coordination along with improved retinal function.
protip_icon Quick fact
At 5 months, a baby’s visual perception can distinguish two tints (lightness) or shades (darkness) of the same hue. The child is also able to see longer distances and show preference for certain colors (5).
  1. Shows basic language development: By the fifth month, the baby’s language development will be right on track. He would have babbling sounds, saying when in a playful mood or when someone calls and tries to make an interaction with the baby. Your baby coos a lot, which now comes effortlessly to him as he gradually develops his communication skills (3). This is due to improved vocal cord function and the brain’s ability to produce sounds from it.

Physical Developmental Milestones

The baby can now roll over back to the tummy

These developmental milestones are about the baby’s physical growth and motor skills.

  1. Better hand control: Things do not slip out from his hands anymore as he has a better grip than before. Your baby will promptly use his hands to pick up objects and will even stretch them to reach objects that are beyond immediate reach. Your baby will also play with his hands while making more nimble movements with his fingers. This is also the time when he will begin grasping his feeding bottle independently. Babies join two hands together or two thumbs together and bring them near the mouth to put it in mouth. Some babies bring their toes near their mouth while holding their feet.

Amber talks about her baby Baker Bree, “She is so interested in everything, very alert and exploring. She had noticed my jewelry and plays with my necklace and earrings whenever I’m holding her.

“She will put her hand out in front of her and stare in amazement as she moves it around…it’s so cute! Her feet are her favorite toy right now. She has been grabbing them for about a month, but never really started using them to her advantage- she rocks back and forth while holding both of her feet (i).”

  1. Raises chest when prone: When the baby is lying prone (on his tummy), he will push his elbows down and raise his chest upwards (4). This action will later help him when he crawls.
  1. Better controlled neck movements: Neck muscles are stronger, and his neck is no more wobbly, which gives him a better control over the neck.
  1. Makes attempts to sit: Your 5 month old baby will make his first attempts to sit by raising his hips or buttocks Your baby will be able to sit if you support his back or make him sit by holding axillaiThe region where the arm connects to the shoulder (armpit). . In sitting, now back is more straighter than before.
  1. Can roll over in one direction: He can now roll over back to the tummy (4). Once he gets on his tummy, he will attempt to flex his legs. This is his way of strengthening his muscles before he begins crawling.
  1. Improved sense of taste: There are now more nerve endings on the baby’s tongue than ever before. Anything that seems interesting goes straight into the mouth. That is a way of exploration for babies as they learn about the world around them. Yes, putting things in their mouth is a baby’s way to explore the world!! It is normal and not a bad habit.
protip_icon Did you know?
Towards the end of the fourth month, children develop a distinguished sense of smell, differentiating good and bad smells and associating them with faces and tastes. Thus, children can differentiate between sweet, sour, and bitter flavors and safe and unsafe people using their scents at five months (6).
  1. Better hearing and muscle coordination: Say something aloud, and your little one will turn his head and look at you in attention. He may not understand his name but understands that you are talking to him. The 5-month-old even turns his head to other sounds that he finds interesting thus indicating improved hearing-muscle coordination.

A mother of four, Kaleigh Carnahan, explains the milestones of her 5-month-old baby, Aynsley, and shows how Aynsley’s father tries to talk to her at every possible moment to improve her babbling. He speaks to her in different tones while changing her diapers or getting her dressed, and she responds with equal excitement (ii).

  1. Sleeps in blocks of hours: The baby begins sleeping longer in blocks of hours, especially at night. This is an indicator of his improved sleep functionality.

Social And Emotional Developmental Milestones

The baby smiles and looks jovial when seeing someone familiar.

Bonding and attachment with people around is one of the milestones your baby achieves as he grows mentally and physically.

  1. Displays recognition of familiar faces: The baby will have an acute recognition of individuals that he had met in the past. He smiles and looks jovial when seeing someone familiar. He also moves his hands vigorously, which is his way of greeting that person. A better long-term memory is the reason for this improved social behavior. You can see it when, baby who is seeing unknown faces, wanders around, finds mother or caretaker’s, recognises her and smiles very cordially and shows happiness.
  1. Shows anxiety towards strangers: Your five-month-old will show his first pangs of anxiety when left in the company of someone he does not know. If you let a stranger hold your little one then be prepared for a blaring tantrum. This anxiety towards unknown people is a primitive display of trust and confidence, or the lack of it, which constitutes the building blocks for complex relationships in the future.
  1. Loves playing with parents: At five months, your baby is more playful than ever before. Roll a ball towards him, and he gets all excited about it. There is a certain excitement that you notice in all his play activities especially when playing involves people he loves and trusts the most – his parents.
  1. Expresses emotions: Smiling will be the most frequent emotion of your baby. He now actively displays displeasure, excitement, and fatigue. He will switch between toys after playing with one showing the first signs of boredom.

Those were the various developmental milestones achieved by your baby when he is a jolly five-month-old fella. Parents can always take steps towards nurturing the physical, mental, and social development of the baby for good health and timely growth.

6 Tips To Improve The Development Of Your Five-Month-Old

Encourage and assist your five-month-old baby’s development through these easy steps and practices:

This will help him have better dexterityiSkillful in performing tasks with fingers and hands. .
  1. Read aloud brightly illustrated books: Make him sit on your lap and read a book with brightly-colored illustrations, aloud. Viewing multiple shades of colors stimulates the baby’s eyes and brain.

Your five-month-old baby will certainly be on a sound development path when his milestones are further sharpened through play and activities. But there are always certain red flags in his development that you must be alert about.

When To Be Concerned?

If your baby is not developing at a normal pace, then he may show the following traits, which are signs of acute developmental backlogs:

  1. Does not respond to sounds: A five-month-old baby may not know you are talking to him, but he will definitely turn his head when he hears his parents speaking. He will show a general interest towards voices of primary caretakers. A lack of responsiveness or an extremely underwhelming response towards sounds could be an indicator of a hearing problem, which you must get checked.
  1. Poor hand control and grip: Your baby has better sensory control of his hands. But if his hands always seem floppy with disconcertingly weak grip then it could be that his muscles are not developing at a normal pace. Poor hand control and grip could be an indicator of muscular dystrophy, and you should let a pediatrician take a look at your baby.
  1. Has a stiff body with awkward movements: If he generally stays stiff and seems to have very poor voluntary muscle control then that is alarming. At this age, the baby prepares to have quality tummy time. A stiffness of muscles can be an indicator of a plethora of problems including serious autistic-spectrum disordersiA group of developmental disorders that affect a child’s social interaction and communication skills. . Do not jump to conclusions though and take your baby to the doctor.
protip_icon Point to consider
Alternatively, if the child has floppy muscles that make them feel like a rag doll, it can be an indicator of hypertonia or spinal muscular atrophyiA condition in which the muscles involved in motility are rendered weak or incapable. (type 1). The condition can be diagnosed at this age (7).
  1. Displays no expression or affection towards parents: A baby may not smile and greet every human he meets, but he is definitely going to express joy and elation on seeing a parent. If the baby has zero expressiveness towards parents, shows no alertness, does not show concern for safety, and does not smile, then it could be a sign of a developmental backlog.
  1. Shows poor speech development: Babies tend to use their vocal cords a lot now. Your baby will keep you entertained with his cooing and gurgling. But if he is always quiet and does not babble, then that is definitely unsettling. It could be an early sign of speech impairment, and the sooner you get him under medical supervision, the better are his chances of subsequent recovery.

Frequently Asked Questions

1. Can a five-month-old baby eat food?

Your five-month-old baby may show signs of feeding by bringing their hands to their mouth when hungry. However, nutrition experts recommend feeding them solids or water until they are six months old (5). At five months, the mother’s breastmilk or formula is enough for them.

2. How much does a baby weigh at five months?

By five months, your baby might have doubled their birth weight (6). However, it is their doctor who can guide you best.

3. When should I start introducing solid foods to my five-month-old baby?

Your baby may be showing signs of being ready for solid foods. For example, showing hand-to-mouth coordination for feeding and losing tongue thrust (10) (11). If your baby shows other signs, such as sitting with support, mouthing toys, and showing a desire for your food, they might be ready for solid food. However, it is not recommended to give babies solids until they are six months old.

4. How can I help my five-month-old baby develop language skills?

Start having conversations with your baby from birth (12). Point to things and tell what it is. If they babble after you have said something, turn it into a conversation. Use a calm, musical tone to talk with them. Talk with them about your daily activities. Reading to them from a young age also helps babies develop strong language skills.

5. When should my five-month-old start babbling or saying their first words?

At five months, your baby will start babbling (13). They will also copy the sounds you make, such as coughing or laughing. They start making raspberries and playing with themselves by making sounds in different pitches. Babies say their first words when they are around 12 months old.

6. When should I start thinking about transitioning my five-month-old from breast milk or formula to other types of milk?

It is recommended to give your baby breast milk or formula until 12 months of age (14). If you wish to transition from breast milk at five months, you can switch to formula. When your baby reaches the age of 12 months, you can introduce cow’s milk.

7. How do vaccines at five months ensure baby safety and health?

Babies aged five to six months should receive the third dose of the DTaP vaccine (against diphtheria, tetanus, and pertussis), the third dose of Haemophilus influenzae type b (Hib) vaccine, the third dose of pneumococcal disease vaccine, the third dose of rotavirus vaccine, and the third of polio vaccine (IPV). These vaccines are essential for protecting babies against serious disease-causing microorganisms that cause infections and have enough potential to cause significant harm. At six months or above, additional vaccines include respiratory syncytial virus (RSV) vaccine, flu vaccine, and COVID-19 vaccine (15).

Rolling over, sitting with support, and improved hearing and expressions are the major milestones of a 5-month-old baby’s development. You may promote their development by following simple methods such as conversing with them, encouraging tummy time and sitting, and introducing different-colored toys. Also, remember that every baby develops at a varied pace, and you must not force your little one to do anything. Instead, let them learn and explore things to achieve their milestones while you are observant of their progress. Altogether, do not hesitate to speak to your baby’s doctor if you feel they are not meeting their developmental requirements appropriately.
