Have you figured this out?
I have a 18 month old and a 4 year old. The four year old like to ride a trail a bike that my husband pulls and my 18 month old rides on a seat on my bike, that is mounted on a sturdy rack. I really want the ability to take both kids with me. I have previously put the 4 year old in my bike seat and the baby in the trailer so that I can take both, but the 4 year old is now too heavy and really wantes to rider "her" bike.
So has anyone figured out how to attach both a trail a bike and a baby seat? I know there is a way and I think we can probably come up with something, but I wanted to see if anyone has already solved the problem. Pictures would be wonderful!
