my son is two years old now still he is speaking only 4 to 5 words it's normal?

A. Ma’am now I think it should be better than this I do agree to the fact that some kids pick up late on their speech but at this age the more you communicate better your child is going to learn I hope you’re not giving any screen time to the child because he can lead to verbal delay of growth which is in good at all so I think now if you communicate more get some educational toys board books/cards teach with those cards play with them and things are going to get better over the period
