The short video was then posted to Facebook where it went viral, sparking death threats, the mom claims.
'I didn't post it on Facebook or YouTube as a challenge or whatever'.
"I posted this on my personal Snapchat with my 20-something friends, where someone allowed another person to video it", Ward wrote.
Cori said: "I do understand [why people are concerned]".
The mum has since apologised, adding: "I know what it's like to have to worry about your kid's health and stuff".

The video appears to be part of a disturbing trend where people film themselves licking food and objects before placing them back on shelves. Behavior like this is unacceptable in Texas & is rightfully punished.
The video shows the man, identified in news reports as Lenise Martin III, licking the ice cream at a supermarket in Louisiana.
Another hand is then seen removing one depressor from the container.
Her husband said he was stunned when he saw the video and realized she was his daughter.
