Hi there. How old is your LO? I am assuming older than 4 months just due to the fact that she is on the 4 hour EASY??
My DD went through a stage of exactly the same thing, I nearly went mad after a couple of weeks of waking every hour or so, plus taking up to 2 hours to get her back to sleep!! :shock: :shock: I can totally relate to what you are going through!
I have no quick-fix solutions just wanted to let you know that I've been there and that "stage" has now seemed to pass, thank goodness!!
Hope it will pass for you soon as well. :lol:
