Re: Why is conversation good for baby?
Conversation is so important for babies. They hear your voice for nine months and need continued "chats" so they’ll develop a language of their own. Studies have shown that babies respond very early to voice -- especially the mother's voice -- and that this is necessary for the infant to later progress through the milestones of cooing to babbling to single words and phrases. Children not exposed to language, even from an early age, can have delayed vocabulary development at school age. And babies love to be talked to, especially sung to (it doesn't matter if your voice is on key!).
