I've got one of the older MB double terranes, I noticed today when I put the baby in the carrycot on one side I can't use the double storm raincover. anyone got one, what did you do to cover the other child, the carrycot has its own raincover so baby is fine. also I wondered if I could use a single raincover but not convinced because the suncanopy on my model is a double rather than being two seperate single hoods? any ideas?
