Hi Faye,
we too are struggling with wake ups that are all over the place. It was ok here for a while, not posted since lo was 19 months but he got chicken pox 3 weeks ago and now all hell has let loose.
We too have no pattern for the waking, sometimes he just has a bit of water and sometimes he is awake for up to 2 hours, so you are not alone, and in a strange way these posts make me feel like ds is normal, cos i really worry at times that its not normal, but it is!!!
I agree with previous posts about gradual withdrawl as wi/wo makes ds livid.
