My nephews love dinosaurs and cooking - kind of random. They are 2 and 3 with enough toys to fill a room! Before I left on a recent trip to visit them for a couple days, I picked up a dinosaur egg that hatches in 72 hours after soaking in water. They could both watch and check on it and while we were visiting. Throughout the day we looked in on the egg and laughed about the forming cracks! They loved it, and I loved watching them laugh and smile!
