You're 3 weeks pp and he's moaning that you're not doing enough cleaning?! He needs to sit his arse all the way back down. There are things more of a priority, cleaning for 4 hours is insane. As long as the house isn't dirty then in that first month or so you accept that the house isn't as pristine as it was before a baby. I'm sorry that you're having to deal with this, when you're healing and trying to look after a baby it's the last thing you need.
Am not going to be the popular thought here... but he went to work, came home and was cleaning and you wanted him to take care of baby, so he can continue on cleaning? Thats the problem?
You shouldn’t have to ask for his help..obviously yall just had the baby and having to clean and take care of a baby is a lot. When he gets home he should allow you a shower and spend time with his child..that’s bare minimum yk..it’s great that he’s cleaning but being alone with a baby is a lot..u deserve a second to yourself too
