Vibe:
Do you find that with the seat fully reclined in the newborn position that the head is lower than their bottom once you undo the zips???? I'm having to have my zips half undone but they don't stay there very well!
Also - where do you buy replacement inner tubes from?
Vibe & Sport:
What's the youngest age roughly that you can put them in the extra second seat (that clips on) at the back (fully reclined)?
