Neither. My husband got me a gardening wagon when he went to the mainland from Costco. I think Canadian Tire has them too. It folds up and carries more weight than toddler wagons, the sides are the same height and the space is the same but it steers much better on gravel and snow. I've had lot of wagons over years and this is by far the best one.

Will add, that once a child is walking here, they are expected to walk most of the way. The wagon is purely for a tired little (not a lazy one) and for putting several in if crossing a street. I do not and will not pull three year old children just for the sake of it. I typically have a child between 10 and 18 months who is expected to walk at least some of the distance if they can walk. Most of the time, I only have one child in the wagon (unless crossing a road).
