My 1.8 year old son rubs his penis on the objects like our hand or knees. Initially we thought he is feeling itchy but its not. I am quite worried about it. Is it normal or not with kids.

A.   check for skin rash, irritation, swelling, redness. but it can also happen as baby starts exploring body parts, they just start to play with it. pleasurable sensation is also possible in baby. nothing to worry about. you can put on a nappy, blanket, deviate his attention, give some toy to play and sleep. be gentle.
