My LO is 5.5 months old and the last three weeks have been the worst sleep of her life. Worse than when she was a newborn even!

LO used to be great at night sleep. She would sleep for 7 to 9 hours at a time, and usually have 1, sometimes 2 night wakings. Her naps, on the other hand, were terrible. She never napped longer than 45 minutes, but they were usually 20 minutes or so. I tried to not make a big deal about it because she was doing so well at night!

However, things have seriously flip flopped. She is now a great napper! She has been taking three one-hour naps a day, although every couple days one of her naps is two hours. This changed out of the blue! BUT as soon as this shift happened, her night sleep went to crap. And crap is an understatement.

LO now takes HOURS to get to bed at night. I am pretty anti CIO, but I have actually let her cry for up to an hour because I am so desperate to get her to sleep. Once she is down, she can't sleep longer than two hours. Throughout the night she wakes every 45 minutes to 2 hours. And the worst part of it all is that she has pretty much lost her ability to go back to sleep after a wakeup. She can't be nursed back to sleep, rocked back to sleep, driven back to sleep, or even swung to sleep in her baby swing. CIO doesn't work either.

This means that she is awake for an hour or so during every single wakeup she has. She basically isn't sleeping AT ALL at night time. And of course I am exhausted. I spend the night hours walking up and down the hallway with her, singing, and softly talking to her trying to get her to calm down so she can fall back asleep.

I usually try to refrain from making sleep posts but this has been going on so long that I just am at my wit's end!

Could she be hurting? She doesn't seem to be gassy/she doesn't spit up. What could I possibly do to change this?

It seems odd to me that terrible naps = good night sleep and great naps = bad night sleep. This is the only correlation I can make since the changes happened simultaneously.

PLEASE GIVE ME SOME ADVICE! I AM SO TIRED!
