How often would you change a mattress?
in my group of friends we have a small tradtion.
when my best friend first fell pregnant with her son who is now 11, we all chipped in and bought an amazing moses basket and crib. the tradition is now every time one of us has a baby we use it and give it back.
i know its been used 4 times in the past 11 years, and i bet money that noone has ever replaced the mattress?
am i right in thinking i should ? or is it not needed?
