Watch my YouTube video I talk about changing a kids poopy diaper as a almost completely blind single mother. https://youtu.be/HqykogJPukY

This question just got asked recently and I'll repost my reply. Here's a link to the discussion: https://www.reddit.com/r/Blind/comments/u692u1/how_do_blind_parents_change_soiled_nappiesdiapers/

If you're the parent who's at home dealing with the majority of the diapers this isn't practical, but since my wife changes most diapers and I only encounter dirty diapers occasionally when my wife is out, I just bath them. First I undress the child completely so nothing accidentally gets on their clothes, then I fold the diaper over the mess and wipe down with it as I go (I do all this on a washable changing mat which I wipe down when I'm done). Then I clean them with wipes the best I can in a methodical downward pattern; I use a lot of wipes just to be on the safe side. Then I bath the child. It's rather time intensive so might not be the best option if you're the one changing every diaper that comes along.

Also, my first child was a girl. Now I have a son and that's a totally different diaper changing experience. I stick a washcloth overtop of him while I'm wiping so he's not going to be aiming right at my face if he goes while I'm changing him (which has happened).
