I'm also looking at twin prams as DD will still use ours quite a bit, DP and i are going to go to a place like baby bunting and look at some, see how well they fold, get them to check if they fit in our car etc and then look at e-bay.

I think i could do with a toddler seat but we can't buy one for ours and saying that Ava will still only be 15mths old and i'm sure taking naps at times when we are out so i am looking at a side by side aswell.
Am thinking a stroller rather than a jogger, love the idea of a tandum but had a look yesterday and the front seat doesn't recline enough and they are still quite bulky... will let you know how i go with my search.. feel free to give me any tips you find!
