DD (7 months) has always been pretty easy to put down for naps and bedtime. We would lay her in her crib, give her the pacifier and blanket and she would fall asleep on her own with little to no fuss.

This past week, she cut 4 teeth, had viral diarrhea, hit a growth spurt AND learned how to pull herself up. We just finished sleep training the week before all of this happened and it was a great success (with only one night of crying). Now she fights naps and bedtimes like I've never seen. If we don't go in, she cries, if we go in to check on her, she'll SCREAM until she can't breathe.

The only success I've had is to nurse her to sleep or feed her a bottle. But I don't want her to use those as a crutch to fall asleep each time. I'm not sure what to do. Crying it out doesn't seem to be working - I've stopped it at 45 min and just go back in to comfort and hold her.

Any tips that might help me get her back to sleeping? Or is this just a developmental thing that happens??
