It's just struck me that all the stuff about getting a new mattress for each baby, how does that work with co-sleeping? DD1 was in an attached bedside crib right next to me for easy night feeding, but ended up in our bed a lot of the time. We won't be getting a new mattress for ourselves when DD2 arrives in a couple of months, but how does that stand re the SIDS guidelines?
And what are you meant to do with all the 'old' mattresses anyway - do people end up with piles of moses basket mattresses?
NB am about to go out for work xmas lunch so if I don't reply immediately please don't be offended!
