Mothers of adorable chunks!

Other mothers with chunky butts how do you handle the creases. My guy has leg rolls galore lol and arms rolls and necks rolls. And he has a rash in every crease. We give milk baths, use aqua for, use diaper cream, pat extra dry and let air out after baths, constantly make sure he is dry. He spits up a lot and drools like crazy always chewing his hands. But seems to just stay red. I feel like a bad mom but I just don’t know what else to do
