So that first baby was a success, and you're thinking about adding a second to your family's roster, but that expensive stroller you bought only accommodates a single passenger who isn't ready to walk yet. You can either give up on the idea of having more kids, or consider this collapsible stroller sidecar that easily doubles your pram's capacity.

Compatible with the vast majority of the brand-name strollers on the market, the Buggypod Lite easily attaches to the side adding an extra seat, without gobbling up as much trunk space as two full strollers. It can support infants and toddlers up to 40 pounds in weight, and comes with a rain and wind guard accessory to keep both riders dry and comfortable. It's just unfortunate that at $160 it's priced well north of many strollers, so only parents with impossibly small cars and trunks need apply. [Buggypod via 7Gadgets]
