I’m not technically a lone parent in that my kids go to their dads two nights a month, but I do all of the actual parenting. Mine are also primary age and my youngest is a real handful with some send.
I couldn’t make full time work for our family, and I constantly felt that none of us had down time, and that I was spending all my free time working.
I now do a part time job 2 days per week on set days with childcare.
And on top of that I do some self employed work which I fit in round life and personal time. Eg I might drop the kids to school, do a couple of hours, go to Pilates, go to the supermarket, pick the kids up, make dinner and then do another hour once they’re on bed. I try to plan my time so I do this term time only as much as possible, and I have no childcare costs those days so it’s all profit even though not many hours.
I am really fortunate that I was in a position in my career, and had enough house equity etc when we split that I’ve been able to make this work. I know that it’s not feasible for everyone and that I’m very lucky.
Day to day two things which make the biggest difference for me are:
having a cleaner 2 hours per week, and all working together to do a tidy on cleaning day. Whilst I still have to wipe surfaces or put on the dishwasher I have so much less to do. I can’t remember the last time I cleaned the bathroom.
Prioritising time for me. Once the kids are in bed I don’t do any chores if I’ve worked in the day, and when they’re with their dad I’ll only do specific jobs ( eg I might spend the day painting a room but I don’t clean up spilt weetabix). It took me a while to work out how to do this but I’m now good at sorting out in the evenings before they go to bed and in the mornings of days with their dad so that this doesn’t cause too much havoc.
Not sure if that’s what you’re looking for but that’s the best balance for us. Still not perfect and we occasionally end up with toast for dinner, but it doesn’t feel as hard as it might.
