The girl told police she initially consented to the arrangement but later decided she didn't want to follow through, Gill said.
The mother also admitted to taking the girl to a Victoria's Secret store, where she opened the dressing room door for Don to watch the girl model bras and thong underwear, Gill said.
The woman is also accused of sending pictures of the girl wearing lingerie to another man in exchange for money.
The negotiations for the pictures and the sex acts are alleged to have occurred from April 1 to May 18, Gill said.
Gill would not discuss details of any investigation of the man known as Don or the other man who received photos of the girl. He would not comment on whether police have identified those men or whether their ages are known.
The woman is charged with two first-degree felony counts of aggravated sexual abuse of a child and two second-degree felony counts of sex exploitation of a minor.
The Tribune is withholding the woman's name to protect the identity of her daughter.
