I worked one summer at a camp and one week we had a little girl who latched onto the woodworking counselor, and acted very much like this girl. She followed him around everywhere he went as much as possible, and would try to cling to him. The adults that came with the group would have to drag her away at times to give the poor guy a break. She didn't call him daddy, and definitely didn't try to undress in front of him, but all the rest is realistic.
