Newborns can cry. After a few weeks, they can gurgle and make small sounds. Gradually, they begin to coo, babble, and laugh.
The best way to help babies learn to speak is to talk to them. Speak and sing to your baby as much as possible. Talk while feeding, bathing, and dressing your baby. Talk about what you see while taking a walk. What you say is not important, what matters most is that your baby hears your voice.
