Been taking my daughter to indoor playgrounds
Taste safe messy play is our go to when we can’t get out the house. I just fill one baking tray with a bit of water and add some toys and fill another with things like rice, pasta, oats, whipped cream etc and let her explore
Maybe some sensory play? We’ve filled the bath with a half inch of water and let him crawl/splash around. Or filling a gallon ziplock with water and toys and taping it to the floor
