Not Speaking 22 months boy. Channa etc.

Hi, My son is 22 months old and only say papa mama and shout and scream when we dnt agree with him . point to his stuff food water . Tv toys etc. he like. Doesn't listen his name we have done bera test for confirmation but all normal. Not much emotionally attached with family members. Recognise us but dnt point when we ask who is papa mama etc hv normal diet. I am worried with so much stuff online to guide. Do bye bye n Flying kiss when we say or by himself when he want continuously. copy us what we are doing like sit and making roti. not much with kids but play with us.. Mostly running game cycle.. not much in playing toys the way they are.. Can anyone guide me properly.. Smile to us.. Cry for breastfeed. Eat roti , roated channa etc..
