We've recently added a few toys to my sons toy rotation, after nearing 18 months and he was outgrowing some of his more simple cause and effect toys. We've noticed he's into more action style toys, toys that encourage imaginative play and imitating us in play with his toys. We wanted to find more toys we could interact with together with building, stacking, sorting, etc. These toys have all passed the test for this age and an added bonus is that they all stored easy and didn't take up a lot of space when put away !
