That's terrible.
Sadly, that happened to a girl where I used to live.
Her water broke in class and as you may know sometimes bigger girls aren't as noticeable when pregnant.
All of the kids laughed at her, they thought she wet herself.
The next day, the cleaners emptied a sanitary bin from the girls toilets and found the baby in there...Sadly not alive.
It was reported that the baby wasn't miscarried. It was alive when she put it in the sanitary bin.
They urged the girl to come forward, she didn't get in trouble. But they found out that she already had, had other children and left them with her mother.
I don't see how someone can be so irresponsible and have done this to another child.
I know this story because a close friend of mines father was the main officer in charge of the investigation.
I have the link to the news story here too.
