Hi all I've recently purchased the babylo maxi Cosi in preparation for my first baby and have learnt since that it's nearly impossible to buy sheets and mattress protector for it! Explains why it was cheaper than other brands! According to my partner the mattress is 88Lx51W (cm). I've come across a set of fitted sheets with protector on Amazon that's 90Lx55W. Would this be just as dangerous as sheets that are too small? I've tried looking for flat sheets instead which do exist however none of them come with a mattress protector.
