Im a parent and it really depends. I still connot stand to hear a baby cry. A child of about 5 or 6 was getting bloodwork absolutely having a meltdown, you could hear very clearly from the waiting room. I was on edge the whole time.

I have more patience for it, more empathy for the parents (just because a child is having a hard time doesnt mean the parents are shit), I still connot stand it though.
