The evil thumb has found my daughter

So I'm sitting on the couch watching tv and Isabella is laying on the floor watching tv also. I hear some sucking noises coming from her and figure she's just sucking on her hands like she usually does. I look down at her and what do I see??? Her THUMB is in her mouth!!!! She finally figured out how to get it in there. Now, you may not think this is a big deal, but to me it is. I sucked my thumb for YEARS, and had to get braces because of it. I know how hard it is to stop sucking your thumb, and I don't want Isabella to try to have to stop. So I immediately pulled it out of her mouth and stuck her pacifier in. I saw her do this a few more times throughout the day, and last night when I went to bed I looked at her sleeping in her crib and sure enough she was sucking her thumb. I don't know if having her suck on her pacifier is better than her thumb, but at least one day I can throw her pacifiers away. I don't have any way of getting rid of her thumb. She likes her pacifier and usually only needs it to help her get to sleep so hopefully if I keep sticking it in her mouth when she starts sucking her thumb she'll learn not to do it anymore. As much as I don't want her to suck her thumb I have to admit it is really cute. Maybe sometime when she is doing it I'll take a picture before I take out. Maybe.
