If you got the rumble seat for the UB Vista (older model, no recline) when did you start putting the baby in the rumble seat? G is almost six months old but still seems so little to put in it, but I'm also that mom who didn't turn my first to face out in the stroller until she was almost a year.

Also did you have problem with the big kid kicking the baby (intentional or not) when the baby was in the rumble seat facing the big sibling? Was it noticeably easier to push and steer with the smaller one in the rumble seat?
