#asktheexpert My baby is 17month old. She says only some simple words like, mummum, baba, didi, dida (nani), aay (come), jaa (go), paap (word of scolding) (these are bengali words because we are bengali). She doesn't form any little sentence other than these words like other toddlers of her age. But she is very intelligent, repeats any actions which we teach her, learn quickly anything. Also walks and runs normally, behaviour is also normal. So is there any signs to worry?
