It’s so so tough but keep on in there <3
I know someone who divided up toys into several boxes, so day 1 only box A can be played with, day 2 box B can be played with, day 3 box C then rotate back to box A. Easier said than done because there will be a moment where any kid DEMANDS a particular toy that’s in a different box! But just because you cave on a particular day doesn’t mean you can’t try again the next day – under these circumstances you’ve got to be kind to yourself as well as your child.
If you’re going for a walk somewhere safe and enclosed like a park, you can take a scooter or tricycle. Encourage little races that you make minimal effort in – eg “last to that bench is a rotten egg. Oh I wonder how fast you can run to that tree and back to me (2 mins later) I’ve seen you run faster than that – try again!” A fairly simple way of you having a stroll while little one burns off some energy. Maybe try the morning YouTube PE sessions that are available and treat your trip out as a reward. Maybe in the morning over breakfast make a to-do list together, if you can try and include her in “grown up things” such as when you’re sorting the washing she needs to match up the socks…even if they don’t need doing it’s something different to distract her while you’re being productive but she feels like she’s helping mummy. and once the things are ticked off (by her) only then can you play out. I honestly think that thinking of things to do can be just as tiring for parents!
but top of the list, be kind to yourself, none of us expected to be facing isolation as a single parent.
