Snape follows Dumbledore to the bathroom page 606 >

It blows my mind how many people I see out in stores, restaurants etc that just completely ignore their kids. The typically young kids are following way behind and the parent is just not looking back or paying attention. This person is garbage for acting this way. >

I’m so overbearing in public places. I won’t let my kids out of my sight. It annoys them, but better safe than sorry. You just never know, people are crazy. Seeing kids unsupervised gives me anxiety. >

If she turns to violence that fast those poor kids home life must be awful. >

The kids probably didn’t ask to go to the bathroom because they knew mommy was already pissed off and didn’t want to have her anger directed towards them >

The video has been posted of what she did in a couple of other subs. It’s clear from the video she didn’t care about finding her kids. She was already irate before her kids wandered off to the bathroom.
Edit:
here is video of the incident >

Wandered off or hid in fear? >

Yep, that's what I thought after seeing the video. Those poor kids know her temper and know to hide
