Hello everyone, moms ?? Son is 5 years old. The extreme skin doesn't move away from the word at all, but he writes well, nothing bothers him, I always tell him in the bath to wash himself a little bit inside and stretch the skin, but so as not to hurt... my friends have sons, they all open up already... I'm worried, can you tell me maybe to a doctor? But I'm afraid of surgical interventions...
