I hope you don't take this the wrong way October. But
THANK GOD your having a crappy time too. I've just been in tears again with her trying out PU/PD it did only take 20 minutes, but now i don't know how long to leave her asleep for i've have tended to find if she sleeps much past 3.30 (in 5 minutes time) she doesn't want to go to bed at 7, then there will probably be an hour of struggling to get her to sleep on top of that.
I haven't read the whole section on PU/PD yet so i was really unsure of everything I did and just as i was thinking to myself "well she can't be tired then, maybe her naps are changing", i put her down and she rolled over and went to sleep.
SHe is a determined little thing, and VERY active, she is just learning to crawl now, but gets distracted by wanting to stand up as soon as she is at the foot of something she can pull herself up on. But she is sooo good. But she is so not happy at the moment.
Please tell me this stage won't last long? (hugs to you too!) xx
