my 14months old baby use to suck his thumb while sleep time. Is it normal or not? I am worried about his thumb sucking behaviour. I don't know what to do

A. Thumb sucking in infants is a very normal phenomenon and its called mouthing reflex and nothing to be worried about it just maintain proper hygiene and with time this thing will go . In the toddlers thumb sucking habit is also seen many a times which could be phycovulogical cause and feeling of insecurity or some stress . Just try to make the child comfortable and divert in some activities also spend good time with the child . In extrgeme case withdrawal can be tried with some solution available which are bitter like femite lotion . It needs to be applied locally .
