a mattress protector sheet?
I need to start night time training with my 3 year old as we've been putting it off for long enough now. First we had DS3 on the way and didn't want to upset DS1's routine as we didn't think it would make the night time training successful, then it was winter and not an ideal time for getting wet bedding dry, and then DS3 arrived and we all had to try to get into a new routine with him!
I've finally got to a point where I feel everything is pretty much in order and now is a good time to start. He's excited about wearing underpants for bed and the weather means I can get bedding dry much easier.
I would like to buy a protector sheet just so we don't ruin his mattress in the process as it was quite expensive and I'd rather pay for a protector sheet than a new mattress!!
Any ideas where I can get one?
Thanks
