Right, I know the advice is a new mattress for each baby but is this only for the first bed ie moses basket or for the cot too? We spent quite a bit on dd1's cot mattress and wondered what people think about using it in dd2's cot too? I am tempted as it seems in good condition and is definately better than the one in dd1's cot at the moment (which is an RAF one as we are in the services overseas). We were about to but a new one and then wondered if we really need to. What do you think??? It has a washable cover if this makes any difference. Thanks.
