My baby is 1yr 9 m old and still she speaks that I could not understand. She doesn’t speak like us when she will?

A. Usually kids start speaking well in this age and they can communicate also even if it is one or two words for communication they can use if your child is not yet communicating to you and not speaking much of words then also check if the child is making an eye contact and all because if I contact is not responding is not proper then you need to consult your doctor and which speech you need to communicate more and more child doesn’t pick up by 2.5 years and consultant speech therapist
