Four month developmental milestones
Dan Brennan, MD posted:
At four months of age many babies will start to laugh and squeal, adding to the happiness of your day.

Their hands tend to be more open (and less fisted) so they will be interested in reaching for objects and may try to bring it to their mouths.

If they get enough tummy time, you should expect to see your 4 month old attempt to roll from front to back.

At 4 months, babies are much more social and you will notice that they are generally happier when they are upright and can see what is going on. You may notice that feedings take longer if there are a lot of distractions, like older brothers and sisters playing in the same room.

Enjoy this time with your baby, the fun is just getting started
