Before I begin let me just start by saying that crying is actually the first sound that your baby's gonna make. So your baby can't speak and can't tell you what they need but your baby can cry and crying is a sign that your baby might be hungry. Crying is a sign that your baby might need to be changed or that your baby has gas pain maybe. Your infant should start making sounds by eight weeks of age. We usually call this sound cooing. By four months of age your baby will make cooing sounds and more, a little bit of babbling sounds and laughter. At six months of age your baby might start using consonants or vowels like ay-ya-ya, ba-ba-ba, ma-ma-ma, not specifically but trying to have a conversation with you. At six months you can also see that the baby will have like an inflection in the way that they're making sounds. Sometimes it almost sounds like a conversation or baby talk. Between six months and twelve months they won't be saying words necessarily but they will mimic your pattern of speech. If you notice that your baby is not making sounds at two months of age bring it up to your pediatrician. If by four months your baby is not making sounds, this is a big red flag and you should definitely notify your pediatrician. Speech delay is common and it needs to picked up early because the earlier you diagnose it the more you can treat it and you would want to have a baby's hearing checked who is not making sounds cause maybe they are deaf.
