Meghan got a chariot and is zooming around the neighborhood, spurring on the horses with cries of 'Dada, ride!'.
We bought a trailer for the bike and Meghan loves it - she climbs in, straps herself in and then calls for me to come and ride around the neighborhood. This thing is well made, light-weight and has cup-holders! It also has a 5-point harness system for twins and can be converted into a stroller.
I was asleep on the couch (up late helping with babies) and she came and woke me up to tell me we were going for our second ride of the day..
Of course, being the helpful mini-engineer that she is, I couldn't just put it together and inflate the tyres without some sort of helpful assistance.
