Sydsvenskan reported two cellphone videos show the woman, in the company of other adults, urging her son to smoke a cigarette. She allegedly told the child: "Take a toke then you little … inhale then … come on now. Inhale a little. Light up now, for goodness sake, get the damned thing going."
The other adults present gave the child a can of beer, and his mother did not stop them, Sydsvenskan reported.
"If this gets on YouTube, I'll swear I have no baby," she was quoted as saying.
The Swedish news agency TT reported the 32-year-old woman told police there was no beer in the can, just water. She also said that she gave him a cigarette so he would develop a distaste for tobacco.
The woman has been charged with child abuse and violating Swedish alcohol laws.
