4 to 6 Months
- Your baby's mouth becomes his main tool for exploration. Besides putting everything into it, he is fascinated with the sounds it can create.
- He is becoming more physically active and beginning to socialize more.
Tools for Play:
Exploring with his mouth is a great way for your baby to learn, so let him do it as much as possible. Make sure all items he mouths are clean -- and too large to be a choking hazard. Even if your baby is months away from cutting his first tooth, teething toys in a variety of shapes, textures, and tastes are excellent now. Rolling a ball to your baby is a great way to challenge him physically, says DeLuca. Social games, such as peekaboo, start at about 5 months.
