At week-21, your little one will also start displaying uneasiness due to separation from mother. Your baby could start crying when being passed on to someone else. If this is commonly happening with your baby, you may like to give adequate time to him to become familiar with the people who are new to him. Your baby will say his first words anytime now. He will try to duplicate the sounds that he hears most of the time.
Let’s take a look at some milestones your 21-week-old is most likely to achieve.

You will be pleased to realise that your baby’s appetite is likely to increase. You may want to feed your baby in a quiet and peaceful environment as he is less likely to get distracted by his surroundings and may eat better. The feeding pattern, however, may change during this week. Your baby may simply drift from feeding into a nap. The number of feeds may reduce as the baby because the baby prefers to sleep during feeding time.
You may be tempted to introduce solids into your baby’s diet at week-21. But, it is essential that you continue feeding breast milk for a few months after weaning your baby onto solids. At this age, breast milk is enough to meet the nutritional requirements of the baby if he is fed on time and for the required number of times. There is no urgency to introduce solids as yet. It is quite common for babies to resist breast milk a little as they develop an extra preference for solids.

In spite of the sudden change in your 21-week-old baby’s sleep pattern, the sleep schedule might start getting regular. Here are some of the key points about the sleeping patterns your 21-week-old baby is more likely to have:
- Your baby may not sleep throughout the night, but he may sleep for longer hours during the night.
- Most babies wake up during the night because of thirst and hunger. Usually, breastfeeding your baby should help him settle down and get back to sleep.
- However, his naps may become consolidated during this stage. He is more likely to take chunkier naps (around 45 min) instead of frequent small naps through the day.
- It may not be a good idea to feed your baby too much before sleep time in the hope that he sleeps throughout the night. Overfeeding can cause colic and may lead to added wakefulness.
- Sleep regression in 21-week-old babies is typical of this phase. If your baby has been sleeping well at nights but unexpectedly begins waking up in the night or develops napping issues, he may be undergoing sleep regression due to growth spurts.

Games and Activities
Games and activities bring about physical and mental development in your baby and help you bond well too. Here’s a list of some games and activities that you can enjoy with your baby.
- Ground Time – Place a mat on the floor and let your baby enjoy an extended mat time. You may put him on his back first and let him roll and flip as much as he wants. Most babies, at 21 weeks, begin to explore and slowly start discovering their surroundings. An ample amount of supervised ground time can ensure he is safe and can explore most of his surroundings as compared to his time in the crib.
- Sitting Up – Help your baby sit up in between his ground time. Place some pillows all around him to support him.
- Trace the Direction of the Sound – Get a rattling/ musical toy and shake/ play it to make some sound. Keep doing it till he looks in the direction of the sound. Change the direction every time he traces where the sound is coming from. You may also do this activity when your baby is sitting up.
- Sounds –To help your baby pick up sounds, talk to him as frequently as you can and ensure he is looking at you when you talk to him. Eventually, your baby will imitate the movement of your lips and even try to make similar sounds.
- Keep Them Entertained – No, you don’t have to set up a performance for our little one to entertain every day. All you need to do is have enough bright coloured toys, preferably something they can chew upon, musical toys, roly-poly toys, etc. that can hold your baby’s attention.
- Baby Games – Play games like peekaboo, itsy bitsy spider, the little piggy, where is the toy/ object, etc. to continue building his skills.
