I will have a newborn in June and DS will be 17 months so need to start thinking about prams, I feel clueless about doubles/tandems and don't want to make a bad decision buying one, can anyone offer advice? Do I want one that takes a car seat? Tandem or double? Converts between a double and a single? Ideally we would like to spend £300-£400 although could spend more if needed and I don't mind getting a second hand one. We do have baby and toddler car seats already so not bothered about a travel system and it will be to fit in the boot of a Kia Sportage
