Maddie and Lena finally outgrew their tricycles.  It was a little gut wrenching to see their first bikes go, but their knees were at their ears when they were pedaling.  They both were so top-heavy on the bike that they kept tipping over, so we decided it was time to move on.  They each picked out their new bikes (of course they chose the exact same one), and they are warming up to them.  Lena took a little spill on hers the second day we had them, so they have both been a bit timid.  M and L had  a good ride this last weekend while my parents were here.  We were pretty impressed how quickly they are catching on.
