My daughter was once a good sleeper and then the dreaded 4 month sleep regression set it.  We thought that part of it was due to her acid reflux, but now that we're getting that treated she's still having issues.  She takes a pacifier and needs the pacifier or nursing to drift off.  I bought the sleep guide and tried the 'Chair' method, it didn't seem to make a difference unless I gave my daughter her pacifier.  I would let her cry until she was getting increasingly upset and then would give her the pacifier but I feel like this is doing more harm.  Once she is down (at the beginning of the night) she usually sleeps for about 3 hours.  However, after she wakes she will not sleep in her crib for more than 15 minutes.  She wants to sleep in my bed and I've even gone so far as to put the co-sleeper back in my room…that sometimes won't even work unless I lay my pillowcase down and trick her into thinking she still in my bed.  I've also tucked my pillowcase over her cribsheet so she can smell me.  I work and commute an hour in so I need to get some sleep, however I can get it.  I suppose my questions are the following:

1.  How do I wean her from needing to pacify at night?  She constantly is waking for me to give her the pacifier and wants to nurse if she gets too upset. 

2.  If I'm trying a sleep training method such as the 'Chair' method, should I implement the same tactics every time she wakes up or is it just when she initially goes down?

3.  If she is so hooked on the pacifier, should I wean the pacifier first and then try sleep training?  (i.e. let her lay with me to sleep, if she'll do it without a pacifier until it is not needed at all, before implementing any type of sleep training.)

By the way, we also still swaddle her in the swaddleme blankets.  She will not sleep for more than 20 minutes if we don't do that.  Maybe that's a topic for another time….

Thank you for the help!
