Help please

I’m not a SAHM, but my husband is a SAHD as he is disabled. I get upset at him because I feel like the brunt of the housework still falls on me. If there are any disabled SAHMs in this group can you help me understand some realistic expectations for what might get done in a week. I know that taking care of a child is a lot of work, and that my husband will have good days and bad days. I guess I just need to hear from someone else that my expectations are too high.
