Need more stroller space? Check out our round-up of tandem buggies

Your family is expanding and you need a double buggy, but where to start? First, you need to decide whether you want a twin buggy - where the children are side-by-side - or a tandem - where one sits in front of, or above, the other. It can be a buggy minefield out there, so we've done the research and rounded up a selection of five tandem buggies that will accommodate your growing brood. All you need to do now is decide which one gets the thumbs up. 1. Baby Jogger City Select Despite its name, The Baby Jogger City Select is not intended for jogging. Instead, this versatile buggy was designed to keep your family rolling as it grows from one child to two, or even three (using a glider board). The City Select Second Seat Kit easily attaches to the buggy to convert it from a single into a double. The kit includes the second seat and the second seat mounting brackets. With over 16 possible configurations, you can select the seating positions of your two children - front facing, parent facing, sibling facing; whatever you need. 2. Stokke Crusi The Stokke Crusi chassis can be converted into a tandem by adding the Stokke Crusi Sibling seat to adapt to a growing family. Sibling Seat features:

• Suitable from birth to a maximum weight of 15kg.
• Soft padded seat.
• Hood with visor.
• Two way feature.

3. phil&teds navigator The phil&teds navigator double kit is the second seat for the current model navigator buggy, which features a hands-free auto stop safety brake. It can be converted into a rear facing seat and includes a moldable head and neck support, one hand seat recline, and a sun cover. The navigator buggy features 26 riding options to create versatile, comfortable seating for one child, twins, or two different aged children. 4. UPPAbaby Vista The Vista Rumble Seat was designed exclusively for 2009 and later model Vista strollers. It can convert a single stroller to a double in seconds. Rumble Seat features:
