Ugh!!

I'm good with my MIL, we get along well but I'm always catching her making some slick comment about my parenting or my wifely duties. My 3 month old has been sick for a couple days now, stuffy nose, coughing, throwing up. My 5yr old is also sick with the same cold, minus the vomiting. I've been keeping both close to me as they're both very miserable right now, which allowed me to pick up the germ, so I'm now trooping through a fever, body aches, runny nose and cough. My husband finally got his off days and he's helping out. A few minutes ago, I hear him on the phone with his mom, they're talking about the trip she's taking in a couple days, her sick grand children and the weather. At this point, I'm not even listening, I was surfing this app 😊. Anyway, he said that he's going down to the laundry room and he'll call her back. She goes (not knowing I'm in the room) "why you doing laundry, what happen to Janelle's hands, she handicap?" 😒. He looks at me cuz he knew I heard. He went on to explain that I've been washing and disinfecting every surface throughout the house for days now and he's just doing his part like he always does, plus I'm not feeling well. It irritates me that he even has to explain why he helps out around his home. He lives here right, smh. She's always making these kinds of comments but he's always quick to defend me, I just wish he didn't have to. We're a team and we support each other, there's no his role or my role, we do it together. I had no idea that that was a bad thing.
