2 is a good time to start weening her from the thumb. My daughter really struggled with this and didn't stop her night time sucking until she was 6 or 7. The dentists were going to have her wear an appliance at night and didn't think she could stop on her own. She did have a severe open bite and has finally had her braces off (temporarily) after 3 years of wearing them. Yes, this was caused by the sucking (I think she was also sucking her thumb in the womb :) We prayed together about it, and I asked her permission to remind her if she was doing it (it really doesn't work to nag). I came up with a silent signal (a thumbs up and I'd tap my lips with the thumb) and she'd get the hint...she wanted to stop. At night she'd tuck her thumb under the pillow, but by morning it had worked its way back into her mouth. The final blessing that helped her conquer it, was a severe head cold and she couldn't breath if she was sucking her thumb at night. It took care of the problem and the dentists were amazed and happy to skip that part of the treatment plan and we were happy not to have to pay for it. You know what your daughter responds to. Go with your insticts. And Good Luck!
