My son is 2 year old. He says babba, tahtaha something and all. But still can’t form a word. He doesn’t repeat whatever we say also. But he remembers the song we sing for him. He replies in song tone only with his own babba pappaap like that. He is very very active. Doesn’t sit in single place for more than 5 min. He will be roaming roaming. Is this speech delay normal? #simbamyson
