Such a bad thread to read just before bedtime!!! We're at M&FIL's and Caty's using a mattress that has to be about 10 years old or something.....not good! How do you tactfully ask them to get a new one (or buy one for them yourself) without the whole 'well no child has died in it yet' response you're bound to get?! Aah, two more nights hopefully wont get her!

What if there's heaps of layers between bubs and the mattress?
