I have 3 DCs and am relatively senior in consulting at one of the big global consulting firms.
I outsource as much housework as possible, so that I don’t spend my precious home time doing laundry and mopping floors.
I try not to think about “work time” or “family time”, knowing that both are full time jobs. So: I don’t hesitate to volunteer at my kids’ school every now and then during traditional work hours. I block evening time most nights when I’m not travelling to have dinner with the DCs and put them to bed, and then go back online when they’re asleep. Instead of going out with colleagues for team-building, I often host colleagues at my house for family dinners.
My DH is WFH, so he’s typically the one to do nursery drop off and pick up, and to look after DCs if they have a mild bug and need to stay home. We call him the “default parent” responsible for the daily grind. I’m then the “extra parent” that tends to do aaaaaaall the ad hoc stuff. Doctor visits, dentist, parent-teacher visits, school registration, school volunteering, birthday party organizing, holiday planning, kids’ play dates, hair cuts, making sure they have clothes that fit for every season, days out, etc. It adds up to a lot, but because it is less time sensitive, I find ways to work my way through it (pun intended). Not going to lie though - having my spouse able to take on a 60% load is pretty key to this being viable. I could never pretend we’re truly 50/50.
It works for us, for now. DCs are 6/4/2. I am considering going part time when they’re a bit older. I’ve heard from a few mentors that being around and on call for teens is arguably more important than for toddlers, and I think I buy that. Logistics also seem to get harder when they’re older. Right now the three DCs go to the same nursery inside my DD’s school. My eldest plays one instrument (my DM brings her to her lesson after school on Mondays) plus swimming on the weekend. Once we have 3 older kids doing different sports and music lessons, I suspect I’ll need to be more hands on.
