Because it's Sunday

First, you're doing amazing mama!

Second, be doesn't get an opinion unless he is in charge of the kids. Period. He wouldn't like it if you told him how he should do his job.

Obviously don't tell him it like that haha. But just be open with him and say that you won't be changing this routine and that it works well for y'all. And that if he has a different opinion he is more than welcome to be fully in charge on Sundays.

And it is very hard to have balance with kids while being pregnant, but rest is more important than a clean of organized life or house. So please listen to the rest part.

Maybe lower the screen time. I'm also pregnant and homeschool my eldest two. We do one movie that Mom choses every other Friday. I really recommend cutting back on screen time. Maybe you can find toys and activities for the children to do while you rest laying down next to them? I was just surviving in the first trimester and let them free people

I'm sorry he isn't being supportive. That's difficult. I'm also homeschooling, and pregnant. Sundays are the day we all just stare at a screen for a while. Trying to be on all day everyday without a break is exhausting. Don't feel guilty about the screentime if it is really just one day a week. You know what's best for you and your kiddos. Guys just don't get it, even if they're well-intentioned. Praying for you!
