How do you stay sane working remote + being primary parent?

My wife goes back to work in 2 weeks and I'm staying home with the kids (5 and almost 3). I'm trying to stay excited about this but I'm also panicking. I work full time remotely so I'll need to manage both. Logistically I don't know how this works. Anyone juggling both? Do you actually get real work done or is it all just chaos? Should I be more nervous?
