I think we threw the crib matress out after Abbie was finished with it coz it was only a tenner or something.
Have ages before I have to worry about this... what am I like?!
Like a year and more for the cotbed version!!
Taken from fsid.org.uk:
"Mattress
It is very important that your baby’s mattress is clean,
dry, firm, flat and well fitting. Ideally you should buy a
new mattress for each new baby. If you are not able to do
this, use the one you have as long as it was made with a
completely waterproof cover and has no tears, cracks
or holes."
Will likely buy a new one in the end, but it's interesting reading the completely opposite ends of the scale type arguments in places.
