<s>[INST] My 3 year old son still wears diapers at night. All the sudden a red cluster of bumps show up around the skin above the penis and in the crease of his leg and hes scratching them. Is this possibly diaper rash or something to be concerned and checked out. [/INST] Your child is likely to be suffering from diaper rash which is basically contact dermatitis that occurs when the skin gets inflamed due to constant contact with the moist nappies. Often it gets some secondary fungal infections as well. The solution would be to keep the area dry and open for sometime if feasible. Candid (clotrimazole) powder may be used. With the mentioned steps, things should soon improve and there should be no reason to be concerned. But it can worsen if no steps are taken. </s>
