Query: Parent of a 3-1/2 year-old

The Thomas and Percy Carnival Adventure toy is a waste of money. It falls apart at the slightest jostle from our 3-1/2 year-old boy, upsetting him and frustrating us, because we have to keep putting it back together. It is unsteady at best, rickety at worst. It's obvious the toy manufacturers don't test these things out on children (if they test them at all). They just don't hold up under real-world use.
