Hi,
I am thinking of either getting a Tag-Along or a Tow Bar so that by 4yo daughter can come along for longer rides. Hopefully you can answer some of my questions:

- Is 4yo too young?
- Which is better? Tag Along or Tow Bar?
- I like the Tow bar type because that means she can ride on her own on certain areas.
- Tag Along seems more comfortable
- Can the tow bar work with a 12" child bike?
