I went with a mattress protector, which I kept on for the first few months also as newborn bubs tend to make a bit of a mess too and it is really delicious to spend time in bed cuddling, feeding an just hanging out bonding with bub.

It was not something I considered before the arrival of DD, I only considered waters breaking as my reason for protecting my mattress, but I was so glad I had it on when DD did an almighty spew that first time!
