HELP! My daughter sucks her hair.

Hi guys. i need help. my daughter started off by picking up hair off the floor and sucking on it. now shes graduated to pulling it out of her own head and sucking on that. she doesn't eat it she just wraps it around her thumb and sucks away. its really quite clever how she does it but geez thats got to be one of the most disgusting things ive seen in a long while.
any suggestions.
oh yeah shes also started asking me for a dummy and she hasnt had a dummy since she was 8 months old. shes now 2 yrs old.

how long is her hair? you wanna totally make sure that she dont eat it as hair dont digest and it will sit in her stomach. a girl a while ago had a huge ball of hair in her stomach as she used to eat/suck her hair and she nearly died.

i cant help i have 3 boys with short hair! maybe it needs to be cut shorter . as to the dummy dont give in she doesnot need it she seems to be looking for a comforting thing

i'd say cut it short. and give her a teddy or a blanket to drag around...

one of my friends at school used to chew on her pony tail. It was gross to watch.

Yep, as I guessed. Another from 2004.
