Awesome. My youngest son and daughter are 2 year old twins. I pull them to and from preschool in the Burley D'Lite when I get the chance. It's about 1.5 miles from home. I double back to drop off the trailer at home and bike another 6.5 miles to work.
My 7 year old son rides a trail-a-bike with me on many outings. He's not ready to ride his own bike in traffic yet.
I only wish I could transport all three at once, since most days I drop all three off or pick up all three. Maybe a tandem with the trailer. I'm not about to attach the D'Lite to the trail-a-bike.
