PND and anxiety sufferer here.
I know I tend to blow things out of proportion but just look for some reasurrance.
My 1 year one did that dying-swan arching-back mega-wriggle all babies do when trying to escape a nappy change. This happens A LOT at the moment.
However, this time I heard her spine crack. It was a bit stomach churning on my part. She didn't seem to notice, no crying or anything. She was able to walk after, both arms and legs still functioning normally.
It would be bonkers to spent the night worrying she has a spinal fracture right?!?
