Teachings the boys to do laundry

My step son is 12 and autistic and he shares a room with my 10 year old son. My step son still wets his bed. It was getting exhausting changing his sheets everyday when I work 60+ hours. Plus his skin was getting so irritated from laying in pee. Especially his legs. I recommended getting him goodnites bedwetting pull ups and when I brought ghat up to my husband he said no and that I didn't care about his son. My husband is also autistic. He was a bedwetter and wss abused his parents and diapers were a punishment for him. I wasn't trying to punish his son. When I brought it up to his son, I told him he could pick the design he liked so he got super excited. He ended up wanting the gurl brand. He LOVES pink and butterflies. Today I decided to try and teach the boys to do their own laundry. My step don got even more excited. Now even though I explained you use the cup to measure how my laundry detergent you put in the washing machine..... My step sin still believes dumping the entire container is the best way to go about things🙃. So he will most likely need supervision doing his laundry by he had fun learning. My son was more annoying about learning to do his own laundry. After seeing that my husband apologized to me and said he understands that I care. So all is well

See Idk if tide pods would work either because his logic seems to be the more soap the more clean.

He's still going to wear them. I don't think my husband was trying to hurt me when he said I didn't care. He just has some trauma and I know that's hard especially with being on the spectrum because he doesn't know how to handle it.
