There are a few nurses in my facility who have arranged to care for one another's kids. They work opposite rotations so can cover for one another. Other than family, your other choice would be a day-care that accepts kids prn, EARLY and LATE.
Try finding a sitter on Care dotcom. We tried that and almost had success. Unfortunately, we started looking too close to the start of school and both our prospects got snatched up by someone the day before we were set to interview. Our issue was finding someone that only wanted 3 days a week (and varying days at that!). We also looking for just before school & after school. That was way too choppy of a schedule for most people. If you are looking for all day care you should be okay. We ended up using an unemployed neighbor. So far (knock on wood) it has been fine. Had someone before that quit with like 3 days notice. Also, do you know any stay at home moms? They might be willing to let you bring you child/children to their house for some easy cash. I had no idea how unbelievably disruptive 12 hour shifts were. I was just psyched to only work 3 days a week. So true that there's a price to pay for everything. Good luck! You are not alone. Best wishes.
We use day care but they are only open 12 hours. If we had to we would find a sitter for other after hours until one got home. Another option is get a live in. Housing food and some spending money in trade for child care and house work.
