Witching hour

Carol

Is there such thing as the witching hour? My 7 week old has been super fussy the past couple of weeks at night. We do bath at 8:30, feed her and then put her down around 9ish. What’s been happening lately is that she falls asleep and we put her in the cosleeper and turn off the lights, and close the door. She sleeps for between 15-30mins and then wakes up super fussy and it’s work trying to put her back down again.

I’m a FTM so just wondering what it could be. Does she just want to be held? I make sure she is fed and full, changed diaper and burped so not sure what else I can do to help her.
