DD (2) has just thrown up all over the bed and it has soaked through the mattress. She is fine - not ill. Just had too much milk before bedtime in ruse with DH to try and stay up until I got in from work. Unfortunately it has obviouly made her sick and the smell as I walked in was awful. Have cleaned up the best I can and have put her in the spare bed but the mattress reaks of sick and sour milk. Any ideas what to do to clean it and get the smell out?
