Your routine sounds pretty good to me! How old is your child? My 2.5yo has just pushed her own bedtime from 7pm to nearly 8pm, and it’s only after she’s gone to bed that I can do the final bits of housework. Our flat is far too small to get away with leaving it messy (and I get miserable and ratty if it is) so my bedtime housework chores aren’t optional. Work means no time during the day to keep our home nice.
If everything is already sorted when little miss goes to sleep, then sometimes I also go to bed at 8pm - and if I do, it’s 50/50 whether I’ll manage to stay awake long enough to read anything! But on a normal evening I get to bed at about 9:30pm. If I’m lucky I’ll just read a couple of things and doze off. If I’m unlucky I’ll lie awake worrying. I’ve got a lot to worry about at the moment.
I totally understand you just wanting to wind down. I don’t think it’s problematic at all, it’s just how it is. If the other parent was around to share the load, you might have more energy left at the end of the day, and you might not have so much to do on your own in the mornings. But he isn’t, so you’re making the best of the situation, and conserving your energy so you can do all the essential things for you and your child.
You have to make sure you get enough rest (and if possible relaxation) to function properly, because apart from any other commitments you’ve got, you’re doing the childrearing work that’s more usually split between two adults. It’s a huge load, but it won’t be this way forever.
Do you mind me asking why you’re asking in the first place? Has anyone suggested you’re somehow not doing enough activities or something?
