My LO is 5 months, I've posted previously about her wedging it in her mouth. She's done it with both the 0-6 MAM and the 6+. 
If she's not completely drowsy when we put her down she just wants to play with it like a teething toy! And even when she is nearly asleep half the time she rubs her face and finds it, which wakes her up all over again!
Any one else weaned the dummy at this age? I read it's slightly easier at this age than later down the line.
Did you go cold turkey? Or is there a gentle method?
My worry is she sleeps through 7pm-6am, and I really don't want to mess that up!
Any advice really appreciated!
