Since I started potty training (started in feb) and got my son started on undies he keeps scratching his peepee .. I asked the doctor about it a few times he laughed and said it’s normal .. still now he’s scratching and even saying itchy and I check there’s nothing no redness or bumps or anything .. I keep worrying myself if he’s really itching or if this is normal .. he’s fully out of pull ups and diapers and only in undies now even at night and he keeps scratching and touching it even especially in the tub he’ll dig his nails in his groin like I feel bad idk if it’s bothering him or he’s just curious about his body. I tried putting desitin or lotions on it but still he won’t stop. Any advice before I bug the pediatrician about it again or anyone have a similar issue with their almost 3 boy?
