DS will be 30 months old when newbie is born. I could get him a skateboard thingy for the mountain buggy but I do a LOT of shopping/outtings etc and I know he will get tired. SO i need a new pram. Am thinking of the strider 4 i think? I want the baby to be able to be on top facing me and toddler under, thats doable isnt it? What other prams can you recommend me? Can the strider be used as the top/bottom double with the captule on top?
