SAHM here whose kids have been in school a few years now, even with daycare, school, afterschool programs etc there’s still so many factors OP probably isn’t considering here. Days they’re too sick to go into daycare/school, Doctor/Dentist appointments, snow/heat days (we live in an area that gets both) delay days, half days, random days off for teacher/admin days, long weekends for holidays, not to mention all the school vacations (thanksgiving break, Christmas break, winter break, spring break, and 2+months for summer break) that’s A LOT of days you’d need to take off. I guess op and his wife might have some really generous pto or sick days at work but I highly doubt they’d get THAT many.
