Are there any people out there who has had to transport a small child in a Burley to pick up a bigger child while transporting the older kid's bike so she can ride home on her own? I would love some sugestions. Bungees on the Burley handlebar? The commute is not far (couple of miles) mostly on dedicated paths and neighborhood streets. We would like to avoid the tag-along train as the older kid prefers riding on her own. Maybe I should get a tandem (more novelty) if I can't find help from the forums. Thanks.
