We were going down the path of a bike trailer, when a few people popped up in here and suggested the wee ride. The negative feedback on the bike trailer was that whatever comes off your wheels can end up in the trailer (unless you have a cover), toys or shoes can get thrown out (again, not a problem if there is a cover) and you have to keep turning around to see the kids.

The wee ride sits in front of the rider, with the baby/toddler sitting actually in between the rider's arms. They aren't cheap, but we bought one (love layby!) and we all absolutely love it. We can hear DD chattering about, she's right there with us. Loads of fun. Good luck!
