DD 6 month old has been waking at 0400 or 0500 for the last month. Tried Wake to Sleep for 3 nights, third night was a little better, but then last night she woke every hour from 0100 til 0500 (including 0300 and 0330). At that point I cancelled the 0400 WTS alarm call! She is never hungry, and waits for her bottle till 0600. If I keep going with WTS, will it work? What time do I do it if her waking is so erratic? Any success stories welcome
