Talking to babies is really a funny thing. Some babies like you talking to them, although they don’t understand what you say or they can not say anything. When you talking, they react to you in their own ways. When they grow to about a year old, they learn to talk. At that time, they can’t talk clearly. After that, it’s the golden age for them to learn to talk. Mostly, they copy what their parents say, word by word, phrase by phrase and sentence by sentence. Therefore, when you talk to them, they can talk to you, too. It’s so funny in this stage. Besides, you should care much about what you say, because their learning abilities are so good. Therefore, you can’t have bad influence on them.
