Parents who are building a startup at any phase... HOW? I will not promote

I will not promote!!! I am fortunate to be in a situation where I can freelance as a sales rep while trying to launch my own startup. I am also blessed with two kids ages 4 and 1. It is without a doubt, the hardest thing I've ever done. I would love to hear from other startup founders and early team members- HOW? I live in the NE region. We didn't have daycare during the holidays. No biggie, get to spend time with the kids and family. Then the day before they go back to school there's a snow storm whoch keeps the kids out of school for a week. After that it's two hour delays two days in a row. The next week is MLK, and then another set of snow which has school canceled the next day and ANOTHER two hour delay for two days. Both kids are picked up by 430 so 5pm they're here at home. There mother works also and we're obviously not in the situation for her to be a SAHM yet. I'm struggling to be able to get quality time to get things done. I haven't even gotten to cleaning the damn house 😒 Tdlr: request / advice, how are parents who are founders able to manage their schedules effectively?
