Izzy is a bit older but far out it's so hard hun. I have to make a conscious effort not to say "no" a million times a day, by rewording whatever it is she is doing, we look after J, we can do painting a bit later, you can have cheese on toast or spag for lunch (instead of NO you can't have a lollypop haha) etc. I have also found that it takes a bit of time but I give her 2 options for lots of things where the outcome will be what I want it to be but she gets choice, for eg. it is time for bed, do you want dad or me to help brush your teeth, because if we jsut say time for teeth she might sometimes say NO. This way she knows there is no way out and she gets to choose, and we get a win win.

She sounds old enough to understand bed time too hun, can you sit her down way before bed time and explain there will be one book, one cuddle then sleep time or whatever you decide, and then get her to choose which one and remind her over and over that it will be ONE story and that is it. It might take some time but if you are consistent and don't give in and she realises you are serious it may work. Iz is a shocker for wanting water, loo, etc. at night. We now give her the bottle in her room, make sure she's gone to the loo and tell her if she calls out and carries on we will have to shut the door so J doesn't wake up. A bit different but hey the bribery might work! Good luck it's so hard!
