Hmm, the little girl in the pics you posted looks identical to Ryleigh. She is a model for Sparkles and Stars Models. I would contact them (here is a link to her comp card on their FB page) and let them know so they can contact the mother to see if it's her dd.
Edit to add* Now I KNOW it's her because one of the pictures is the same outfit that is in the comp card. Didn't catch that at first. lol http://www.facebook.com/?ref=logo#!/photo.php?fbid=148262265237016&set=a.131760610220515.23648.130040890392487&theater
