Scorpio - welcome and I agree you will need a double, I had one with DD2 and 3 and there's 2 1/2 year between them, sold it last month to a MNer. Phil and Teds all the way I'm afraid.
Pebbles - whoohooo on the BJCM I was having a good look at one at nursery today, oh and a Zia oh and a Zapp has anyone else almost crashed into the car in front of then as they were too busy checking out a pram in the street double
no1 - do you definitely need a double? I would be tempted to have 2 singles on holiday if I had DH woth me all the time IYSWIM?
I am in utter love with my Lunamix I am happy for now, also had DD3 sitting in the XT today in the garden but she didn't like it no bumper bar to hang off
