Introducing a dummy in an older baby

[Tanya]

I am at my wits end.... Bonnie was always a good night sleeper until I started co-sleeping at about 3-4 months. Now she just wants to suck on me allllll night I am soooo tired!

The only resolution I can think of is a dummy... I tried water instead of milk, but it just doesn't work, she wants to suck. I have thought maybe I should get up instead of putting her in my bed when she wakes of a night, but I am so tired. I usually feed in bed and when she is finished I put her back in her bed... it usually works, occasionally not. Last night it was every hour!

Does anyone have any experiences they would like to share?
