going to sleep between 11PM and 1AM and getting up between 5AM and 6AM is completely typical for a parent with kids in school.
OK 1AM might be pushing it but by the time you eat dinner, help with homework, do chores, get the kids to bed, and take a bit of time for yourself and spouse to decompress, yeah it's easily getting close to 11PM.
Then getting up in time to get dressed, get the kids up, make breakfast, get them to school and get yourself to work, you're probably getting out of bed at aroud 6AM or maybe 7AM at the latest.
