After much confusion and being told 3 different things from Baby Factory, Baby City and then the MB people at the P&C show...I thought I would ring MB direct and ask them.
I wanted to know if I could put a carrycot on one side of a double MB and have a seat on the other. The short answer is YES. The long answer is not so straightforward.
I have a carrycot that I used on our single MB, but that WONT fit into the frame of a double MB as the frame is narrower. So you can get a single carrycot to go into a double frame, but it is narrower that the normal single carrycot that goes in a single frame. Make sense??
I feel a bit ripped off actually - as when we bought our MB I had a conversation with the lady in BF about this exact thing - when we upgrade to a double at some point would I be able to use the carrycot...and was told YES!
Hopefully this helps those of you out there considering a double MB!
