It's one of those moments where I'm glad my kids are past the toddler stage. I'm in 'bad parent' mode right now and letting them have entirely too much screen time and too little direct supervision, but at 7 & 9 they can handle being mostly on their own all day as long as they have something to do. Biggest problem is that they'd not choose schoolwork on their own :)

This too shall pass, and they probably won't be too much worse for wear as a result. I tend to think primary school is 80% day care anyway :)
