My poor little ds was sick in his cot last night, all over his mattress. Can you please advise if we need to buy a new one (it's from Ikea, so a bit of a hassle!) or whether we can wash it. I am aware that all children are sick at times, am I'm sure that people don't buy new mattresses every time! It's just that I have read a link with SIDS and sicky mattresses, plus, I'm sure that the smell would be awful for him. Please help. Thanks!
