My son, now 4yo, did this at the age of 3. He also sucks his thumb. Before using his own hair he would use mine, he changed to using his own because I cut mine too short for him to play with (because I was going bald). He ended up with a perfect circle bald spot right on top of his head! I cut his hair and grew mine.
Now when he wants what he calls his "yum hair" I pull one out and he loops it through the hand that he sucks his thumb on. This may not sound like a really good solution but at 23mths it can be VERY hard to transfer their dependance from one thing to another. So I would consider giving it a go.
You could also try putting a hat/beenie on her head and tying it on. Again at 23mths she may just pull it off anyway.
I hope you have some luck with this. Cheers Kaz.
