My 25 month old boy speaks more than 100 words, started to join 2 words but doesn’t say mumma papa or any functional word to communicate his needs & wants. The only way to ask for food water milk or diaper change is cry or clingy behaviour, but some time back he started doing gestures if he got hurt or mosquito bitten for a rub or comfort by taking my hand to the affected area, also started asking for help to open boxes or containers or help to solve puzzles by bringing that to us. Is it normal ?
