Our son is coming on 1, but loves playing with my brothers trains, I thought rob would've been an excellent first choice because 1. He's square 2. Thought would be harder to chew on because he was square. When our son got it he was so happy and immediately started rolling it on the floor, perfect size for little hands and Toby is a very easy engine to recognize. He tried to chew him one or twice but he doesn't have steam parts like the regular engines do to be easily chewed on. 100% satisfied, thank you!
