Dear Lybrate user,
Please Relax! It is absolutely normal. Babies at such an early stage discover their ability to vocalize as they see you communicating with them (through eyes and encouraging words). Some babies begin to make some vowel sounds (like "ah-ah" or "ooh-ooh") at about 2 months. Your baby will "talk" to you with a variety of sound this is as normal as responding to your smiles with his or her own. :) This is simply
a way to gain the caregiver's attention.
