Georgie is 3.5 months and had started sleeping through the night, roll over feed at 9.30pma nd then was not waking until somewhere between 5 and 6.30am. That occured for a couple of weeks. However the last week she has started to wake around 1.30am. I've been not feeding her and just putting in her dummy which she does go back to sleep but only for an hour, I can repeat this rountine through to 5-6am when she then asks for a feed. Any suggestions on how to stop this night waking. I'm comtemplating feeding her at 1.30 (or whenever she wakes the first time) and I'm sure she would feed but I'm sure she is not waking because she is hungry.
