By three and a half months, your baby will start to show you whether he or she would rather be alone or with other people.

They can’t say for sure if he will become a loner or an extrovert as an adult.
There are babies who like to be alone or with just a few people, and babies who like to be around a lot of people.
Your 14-week-old baby will learn a lot from the things around him, and his brain will make sense of it all as it works.

He will now be much more interested in other parts of the house and want to take a look at the whole thing.

Your child will get strong enough in the upper body and in the muscles around their neck. It’s possible that he could keep his neck straight and look around for a long time.

While holding your baby on your shoulder, hum and make light noises as you fly around the house.

When he holds in a way that allows him to look back, going backwards can cause a big riot and make him laugh and smile.

If you want to work out, you can hold your baby and stack him on top of a gym ball or big beach ball.

After that, let the baby move around and wriggle a little in each direction while you roll the ball softly in different directions.
