Turns out baby gibberish is a very good sign. A study found more babbling our baby utters, the better reader they might grow up to be.
Babies usually start to experiment with making vowel sounds at about two months and pick up the basic sounds of their native language by the time they are around six-months old. They usually say their first word by one, but don't start making short sentences until they are around two. They don’t normally read until anywhere between four and seven years old.
Of course your pediatrician will know your baby better but if your baby isn't babbling try reading to them more! Of course if you happen to have a babbling baby keep reading to them they’ll be taking over soon enough!
