Baby is beginning to be more interested in things, looking around and listening to voices. Movements are getting smoother, less jerky, and he may have better control over his head and neck. Maybe he can hold his head and chest up while on his tummy. He might even be able to roll from his side to his back. While you're keeping a watchful eye on your little one, you'll be rewarded with smiles.
Smiles usually start in the second month.
When you smile at baby, he smiles back. Even though your baby is still young, he needs your praise and approval. When you get excited about your baby's new talents, he does, too. The more attention you pay to your baby, the more he will respond and be fun for you. Babies need to suck, and sometimes feeding isn't enough to meet their sucking needs.
