DD is just over 2 and sucks her 2nd and 3rd fingers when she sleeps. I sometimes catch her doing this when she's tired in the evening, or just before her nap at lunchtime. I wouldn't worry as she is a good sleeper, but I am noticing her front teeth are starting to move forward. I want her to stop this habit before she'll need braces. DS used a paci until about 2.5, his teeth started to move too. We stopped the paci cold turkey, and his teeth are fine now. Any suggestions for dd?
