Dear doctor, My son is 17 months old and not able to speak properly. Before few months i.e. at the age of 12 or 13 months he use to speak like double words like Mama,Tata,Papa etc.. but now a days I don't know what is  wrong with him, that he is only says like single words only like Baaaa...Paaaa... Aaaaa.. etc.. we are worrying as he is 17 months old. In previous months as above said sometimes he said daddy also. But now a days completely stopped to say those words and only says Maaaa...Basaa...Paaaa...etc. Can we give him Vasa i.e Ayurvedic in a small content with honey. Pls comment.
