We have been working on "riding" toys for over a year with very little progress. For a variety of reasons, Maxwell simply didn't get it and didn't like it. It wasn't a huge deal, but I thought it would be such a fun "mobile" activity for him since he isn't walking yet.
He completely surprised me over Thanksgiving, and it was awesome! I helped him on this lil' tricycle and he moved it around with his feet. GO MAX GO! :)
