so glad to read that this morning, SuperDuper
as regards the buggy, it'll only really be for school runs. So the doorway thing isn't so important, they won't be going into shops in it, just back and forth the school 3 times a day (one in nursery/preschool, the other in year 2).
I just need to be able to get my (half-sized) 1 year old into a buggy with the new baby because it's too far for her to walk and I'd ideally like to be able to leave anyone who falls asleep on the school run (20 min each way, depending on the 3 year old's behaviour) in the buggy to finish their nap.
