At first glance, a Michigan mother named Stacey Wehrman Feeley thought it was funny to see her 3-year-old daughter stand on a toilet at home:

Once Wehrman Feeley learned why her daughter was standing on the toilet, however, she was not in the mood to laugh. She took a picture of the moment and shared the devastating reason in a Facebook post that has since been shared more than 13,000 times:

"She was practicing for a lockdown drill at her preschool and what you should do if you are stuck in a bathroom," Wehrman Feeley wrote in a Facebook post published three days after the Orlando shooting. "At that moment all [innocence] of what I thought my 3-year-old possessed was gone."

"Politicians - take a look," Wehrman Feeley wrote. "This is your child, your children, your grandchildren, your great grandchildren, and future generations to come. They will live their lives and grow up in this world based on your decisions. They are barely 3 and they will hide in bathroom stalls standing on top of toilet seats. I do not know what will be harder for them? Trying to remain quiet for an extended amount of time or trying to keep their balance without letting a foot slip below the stall door?"

Wehrman Feeley argued the value of stricter background checks for purchasing guns, adding that Hollywood PSAs about gun safety are helpful but not enough to stop the problem of gun violence in our country.

"I am not pretending to have all the answers or even a shred of them, but unless you want your children standing on top of a toilet, we need to do something!" she wrote.

Her post has more than 10,000 likes:

Wehrman Feeley shared this Facebook update last week, on the same day that Sen. Chris Murphy (D-Conn.) led a nearly 15-hour filibuster on gun safety. Five days later, the Senate voted against four gun safety proposals.
