All you need to do is change a nappy in time so there’s less mess and less chance of nappy rash

Personally I like to put a new nappy under the nappy what needs to be changed on the right level / position. Then have wet wipes handy and a nappy bag and open the strips from the nappy, leaving it under the bottom whilst lifting the legs with one hand. Wipe the bottom clean with your other hands and put the dirty wipes in the dirty nappy. move the dirty nappy under the bottom away and close the strips from the clean nappy. Fold the dirty nappy together closing it with the strips and put it in a nappy bag and discard. Hope this helps daddy
