I think my DD has been reading some of the same 'how to drive Mum crazy' manual as your little one. i have not got everything sorted but have made small developments.

Do you wear a top when you sleep? Having the breast not as accessible can help cut down feeds.

Are you able to pat or use other settling techniques? We co-sleep too, and now i will try to rub DDs back and whisper sleepy noises before i offer the boob. At the begining, it had no chance of working but slowly it is working and sometimes she will go back to sleep without a feed.

Hope you get a really good sleep tonight. Have you read the 'No cry sleep solution'? It suggests getting sleep however you can before trying to make changes, so you have a bit of energy behind you cos the making changes can be more difficult in the short term.
Last night I had two tops on, and she still made her way in. We read the NCSS and Im grabbing it again from the Library tomorrow. The only way I get sleep now is just to feed every 30 mins, which of course means i get no sleep.
Im hoping a night of good sleep will make tomorrow night easier.
