Hi A., I think she will eventually stop. My 3 year old son sucked on his two middle fingers from 2 months to 6 months and stopped. He sucked on them off and on through out the day and they started to crack and bleed and he stopped. My 7 month old little girl sucks her thumb while she drinks a bottle and when she goes to bed until she falls asleep. i think they eventually grow out of it. She doesn't do it much anymore. Dont force a pacifier, that habbit is hard to break. Good luck and dont worry too much about it right now.
