I have three fitted sheets for the bassinet and I have also been told to use old pillow cases as a sheet for the bassinet also cause they slip right in!

I have three sets of sheets for the cot and two mattress protectors also, but again - I have been told to use the old style nappies under bubs head when she sleeps incase she is a spewer (saves washing the sheets every day)

Those old style nappies come in handy too for
-Leaky boobs in bed (if you planning on breast feeding)
-as a protector for your change table mat so you don't have to wash the protector all the time or if its not a plastic wipeable type
- as baby spew rags for over your shoulder.

I bought the big softies colourful ones and white ones.
