Hey everyone
So I have a second hand nexttome so changing the mattress...I bought one from little green sheep and was going to pop on top of the wood panel with a waterproof sheet on top. Been told the mattress needs to go in the original casing ..there's a white and black cover over the old mattress...is that right? I think new mattress would be too thick...what have others done when changing a crib mattress please?
Thank you
