#asktheexpert hi my child is 2 years 3 months is very active and he is not calling dad or mom by own but if we write or show photo tells dad not mum that too when he is in good mood and he tells A to Z colors @ shapes and rhymes and other words in his style and main problem he won’t respond by calling his name but when I ask for going out he comes does he have any problem ? Why he is slow in speech ?
