Help!-- Aiden has blisters on the head of his peepee! It happened a few weeks ago and we thought it was caused from being in the walker too long- (pressure, temp, and friction.) so we haven't been putting him in it often, and then for only short periods of time. I just changed his night time diaper and he has 2 new ones. They are water blisters, as if he has been burned, taking up about 1/3 of the head. I've been tring to figure out what it can be and keep coming back to their diaper detergent. But I don't see how. I use Charlie's soap and have since Sept. And I've been using these types od diapers since March. The ones I'm currently using at night I got the first week of December. I always rinse, wash, and double rinse. I even ran an extra full cycle with no detergent yesterday. I guess I will switch and hope it doesnt happen again. In the meantime, what should I do for him now?
