Have you discovered Wedgits? I recently ordered a set for my preschooler and kindergartener to use during their table time. What I didn’t expect was that their older siblings would not be able to keep their hands off of them, either.
They love to build with them, I love that they are large and easy to find and store in a Rubbermaid box. No little itsy bitsy pieces we’re stepping on in the middle of the night. They don't break and you can toss them into the dishwasher if they get grimy. It’s a win-win toy!
