I was just coming back to suggest Little People. Nathan got this Little People barn for his first birthday, and nearly 2 years later it's still one of his favorite toys. http://www.amazon.com/Fisher-Price-L...6963975&sr=8-1

Another of Nathan's favorite toys is a ride on/push behind John he got for Christmas when he was 8 months old. He still loves it today and he's nearly 3 now. http://www.amazon.com/Fisher-Price-L...6963975&sr=8-1
