Have a look on Vinted for a Lovevery play guide. I find them really helpful x
Do you have any of the coloured balls from the ball pits? I saw a post earlier about using cardboard to either create a mini golf set, or a tray with a hole in the middle that they hold and roll the balls through. Mine loves throwing 100 balls from his playpen into their storage box. Another thing he loves are stickers - they take so much time peeling and sticking and re sticking.
I’m in the same boat! I get my little one to help with chores around the house which he finds entertaining. I always make sure he has some independent play time, we go out to play with a ball, a scooter, go regularly to parks to play alongside other kids, soft plays for climbing 🤷🏽♀️
