@kaiti I have a 3YO in full time daycare, so a little different but here’s what we do.
I typically work until 4-4:30 (WFH) then pickup from daycare. We usually do something after that (library, grocery shop, swim lesson, gym, errands) and try to be home by 6-6:30 for dinner. I typically cook a from-scratch meal once a week and the rest of the week is leftovers, a quick meal (crockpot or microwave) or something simple like sandwiches & salad.
We start bedtime routine at 8 with very few exceptions. Bath, pjs, brush teeth, books, & lights out. 3YO is typically in bed & settled by 9. Wake up is around 6:30am.
We’ve considered adding gymnastics to the mix, but I’m not sure how I would stay on top of other things like housework & home admin with another evening gone during the week. I wish I had a full 8 hours after work to get everything in before bedtime, but it’s just not possible.
It sounds like something’s gotta give: drop an activity, look into simpler or pre-made/pre-prepped meals, recruit more help from your spouse or hired help…
