Just that. I'm not denying the difficulty of juggling work and home responsibilities, but I often see people on here say stuff like "I manage AND hold down a job, so how can you possibly be struggling?"
Being at home all day with small children creates mess. You can get odd things done, but you can't properly clean your house with toddlers and babies around. Especially if they're terrible nappers. I have to clean when the kids are asleep, the same as working parents, and everything is messier than it would be if nobody was home all day.
Now I'm also doing paid work after kids' bedtime the only possible option is having a cleaner. There's literally not time otherwise.
I'm not complaining about my lot in general. I think there's a lot that's harder about juggling nursery runs, commutes, appointments, kids sick days and so on if you are out of the house, but this particular point really bugs me.
