a few ideas
My MIL bought DS a big John Deere wooden wagon for his first Christmas, and the following Easter, she bought him a small plastic John Deere wagon as his Easter basket ;) (she gets a little carried away LOL).
Anyway, the wooden one is way too big and way too heavy for him to pull even at 2, but he does enjoy pulling around the smaller one. The handle is kid-sized. It is big enough for him to sit in it if he wants and we use a rope on the handle to pull him (this is just in the event the little wagon is out vs. the big wagon and he wants a ride for some reason).
I'm trying to find a pic of it and am having no luck finding it online. I'll keep looking. It is way smaller than a full-sized wagon and much lighter.
Here it is on ebay: (I forgot ours also came w/ the little hand tools and little work gloves)
ETA: Aren't there little gardening wagons sold in the landscaping/gardening sections of certain stores? They don't look exactly like a regular wagon but it might work? My MIL has something like that to use in her garden.
I also saw Radio Flyer has a "my first wagon" that is pretty small that might work but I have no first-hand experience with it.
I saw these with a search, but no idea of how easy they are to pull or what kind of quality they are: http://www.neatsolutions.com/Healthy...rden_wagon.htm
