Oh no Beth - sounds like you are having an awful time. You could try a PUL cover if bulk is a problem. I hear you about the cost of the 'sposies. I wince every time I buy them. DD is such a heavy wetter that I change her in the night even with a 'sposie. The other day she drank 750 mls of water plus 2 bottles, plus 3 breastfeeds (I think she had a sore throat) and she outwet every nappy I put on her even in the day.
Are you sure it's the wetness waking her? My DD1 was a terrible sleeper and I used to be up to her multiple times a night. She was in full-time sposies (I'm more educated now) so it wasn't the wetness for her - she was just a terrible sleeper.
I hope you find a solution and get yourself some sleep.
