While you probably know that playing with your baby is an important way to boost their brain development, it's important to note that not all baby games are created equal. Certain activities, toys, books, and baby games do a better job than others of stimulating tiny brains, getting babies' creative juices flowing, and developing both fine and gross motor skills.

Here are 25 baby games that will keep little ones engaged and learning during tummy time, while sitting in their high chairs, or whenever you want to have some fun and give their growing brains a boost. See our Baby and Maternity Guide for all other things baby-related, from the best baby registry services to the best first birthday gifts.

"Free things to do" is our favorite phrase when it comes to kids' summer activities. ("Cheap" is a close second!) More importantly, kids are happy and worn out playing at a free park or splash pads.
