My son is 17 months old and does not speak much. He understands most of the things but speaks 3 to 4 words only. Is it normal

A. You should just try and communicate more and more with your child the more you communicate better your child is going to pick up over the period so just that is what you need to do and you should not give any screen time to the child as that’s not considered good as it can lead to verbal and mental delay
