for hand sanitizer! LEGOs suspended in a liquid soap dispenser. Fun to put out at a LEGO party or everyday use in your kids' bathroom! I'd probably search for a cuter dispenser, maybe more geometrical, but still such a cute idea!
Create a Peek-a-Boo Sensory Board for your toddler to explore could make this a matching sensory activity. Can be used for toddler who have sensory issues and also a way for parents to help interact with the their children.
