I have a 13 yo and a 5 yo. I often think I have easily managed a third if my body had not imposed a long age gap on me. (I’m now too old for any more).
But then I think, if that third had difficult SEN or disability it would have not been so manageable. And I tell myself I’m lucky with my two, and not to yearn for that missing middle child I was unable to have.
So I could recommend an age gap - it makes it really a lot easier.
I am wfh 4 days a week and one day in the office (45min commute each way).
As soon as one of your kids is about 10 things are much easier, I’m finding. I’m rarely flustered - I’m up at 5.30 for my morning swim while dh snoozes, back at 7am to wake up the kids and makes the pack lunches, prep for dinner and sort out laundry or other chores.
My teen can fend for herself - she takes care of our pets and gets herself ready for school and handles her own homework and travel.
I somehow find time for stories, phonics and maths with the youngest and an hour of play per day (Lego, board games, park or whatever).
I do have a weekly cleaner! Is that cheating?
We have several weekday kids’ activities and at the weekend we do family sports (mainly cycling, swimming, climbing, hiking).
I suspect I’ll look back and think this was the best and easiest time of my life.
