Baby Milestones – 6 Months

Take a look at the surprises that you can expect from your baby in relevance to their mental, physical and social growth. Baby milestones can be sorted into three categories- cognitive, physical and social, and emotional.

Cognitive Milestones

This relates to the magnitude of your baby’s brain development, and intellectual and thinking prowess.

  • Curiosity: Your baby is more curious and eager to touch, feel and smell anything that fascinates them.
  • Basic Sounds: Get accustomed to hearing the usual “Ah”, “Eh”, and other sounds to acknowledge things. These are the forms of polysyllabic vowel sounds.
  • Imitating Sounds and response to calls: Your baby will try and imitate sounds you make or sounds from toys. He or she may also respond to his or her name. (2)
  • Conscious of Self: Don’t be surprised if you see your baby admiring themselves in front of the mirror with glee-stricken expressions. It’s just that they are working on the discerning powers of their brain.

Physical Milestones

Some traits associated with their physical and motor skill capabilities:

  • Vision and Perception: With increased and enhanced vision, your baby will now differentiate between shades and love colourful images. (3) Your baby can also perceive depth and distances to judge and track objects accurately.
  • Handy-Eye Coordination: Your baby can now reach out to an object, grab it, study it and pass it on with increased concentration.
  • Finger Power: Using all their finger, the raking grasp, your baby will now hold tiny objects with a sturdy grip. (4)
  • Sitting without Support: Your baby will now start to sit briefly, with the support of the pelvis, and lean forward on their hands. You will see that his back is also rounded.
  • Supports Head: The neck muscles are now firm, and your baby will stretch their neck and turn around to observe things.
  • Rolling Over: Your baby will now roll over from their back to tummy and vice versa.
  • Support Their Own Weight: Your baby will stand confidently if you hold them up and probably even bounce and dance.
  • Sleep Pattern: Your baby will sleep for six to eight hours at a stretch in the night before waking up for a feed. (5)
  • Solid Food: Your baby will be ready to progress to the next step in their diet regime with solid food by slowly biting and chewing. (6)

Social and Emotional Milestones

This charts out the social skills gained over a period of time

  • Response to Emotions: Your baby will now experience varied emotions ranging from sadness to joy, depending on circumstances.
  • Vocal Expressions: Your baby will now have a typical way of expressing themselves for a particular occasion.
  • Recognition Skills: Your baby will now recognize familiar faces and panic when they spot a stranger.
  • More Play: Your baby will show an inclination to play with you and their caregiver as they are keen on exploring new things.
  • Inspection of Objects Around: The 6-month-old infant has discovered his hands and will soon learn to manipulate objects. At first, everything is mouthed. In time, he will pick up novel objects, inspect them, pass them from hand to hand, bang them, drop them, and then put them in his mouth. This will be the usual pattern for understanding things.


You will find that your baby is becoming increasingly clever when they blow raspberries, grab your face or try to put everything into their mouth. Babies love to hear from you and try to read and chat to engage them in a conversation. Your baby will like the occasional time to play games and will express their irritability when they have had enough. Mastery behaviour occurs when infants feel secure; those with less secure attachments show limited experimentation and less competence.

6-Month-Old Baby Activities

Your baby now enjoys movement-based activities. Some activities to give impetus to her instincts:

  1. Read Out Loud: Any conversation is always welcome as your baby is a keen listener, and reading will gain a lot of attention.
  1. Play Games: Your baby will love games like peek-a-boo, racing to the finishing line by crawling, or the tickle with their sift toys
  1. Sensory-based Activities: Indulge in play that will involve your baby in touching and feeling objects. Play with a range of objects from cloth, blocks, water, and even sand.

6 Months-Old Baby Care

With your baby becoming increasingly adventurous, always be on your guard. Their tendency to stuff everything into their mouth may seem annoying at times but try not to be too fanatical about it. Give them a chance to explore when you are around them. Baby-proof the areas so that your baby knows that it is quarantined. Spend time with your baby outdoors as they will learn to expand their horizons. Be on top of their immunization schedules to avoid any lapses. Talk, listen and respond to your baby all the time to develop a strong bond.


Milk is still the paramount source of nutrition for your baby. However, the iron store built up when the baby was in the womb is now depleting. Babies may not like the taste initially, but you could try alternating foods with pureed fruit or vegetable with the taste they prefer until they settle into their new regime.


A minimum of 10 hours of sleep at night and three sleep routines of 1-3 hours during the day are what your baby needs at this stage. Stay calm and try and establish a pattern to promote sound sleep habits in them. Settle them with strategies and techniques for a few days, which they will habituate to eventually.

Tips for Parents

Infant development at 6 months is not very different from children, and they are at that cute stage of exploring, learning, and seeking new things. Don’t be paranoid about extreme hygiene, as they need to get their hands dirty to learn things. Engage in baby activities for six months old babies to get the best out of their motor and cognitive skills. Keep a check on your 6 months old’s baby weight during your routine visits to the paediatrician.

Each child is different, and this particular phase, which is halfway through their first year, is a radical period. Spend enough time with your little one as it is sure to help you mould their behaviour and monitor their growth.
