A friend, pregnant with her second, is dreading having to get a double stroller but her son (2) isn't quite ready to walk all the time. We spotted this Kid-Sit stroller seat (for sale in the U.K.) and wondered if it wouldn't be a good compromise.
We see many parents in our neighborhood have boards attached to their strollers for older children to stand on when they tire of walking. The Kid-Sit is a similar idea and can be used with the board alone or with the click-on seat. You can read more about it here (it retails for around £95).
Do you know of a similar product in the U.S.? What other options do parents of a toddler and an infant have besides a double stroller?
