Marjorie Jones also will have to perform 100 hours of community service under a sentence handed down Monday by a town justice in Queensbury, on the southern edge of the Adirondacks.
The 63-year-old woman could have spent up to a year in jail for the 2010 incident. The victim is unable to speak and has the cognitive abilities of a toddler.
Jones apologized for her actions but said it was a "playful thing" and meant no harm.
The Post-Star of Glens Falls reports (http://bit.ly/LJmQDL) that Jones was served with a lawsuit from the parents of the girl as she left court.
