I'd wait until little bubba is here like the other girls has said. Once bubs is here and u know what ever the situation is I'm sure u will be able to get the pram u need and sell the stokke if need be.

Also my friend has a 20mnth old and he walks every where, refuses to get in the pram when they are out - so u may find u have very little use for a double pram by then (although he is a very active little guy lol!)
