I *used to* bite my nails..........not exactly a habit in that I couldn't control it........but sometimes, I used to have a sudden urge to bite my nails. That was waaaaaaaaaay back when I was a little girl. Haven't done that in over a decade. My major habit as a child was sucking on my pillow. My mom tells me I had this major obsession with this one pillow of mine as a toddler. I had it with me ALL the time........holding it, with the corner of the pillow AND my thumb in my mouth. My mom just could NOT make me stop. She couldn't wash my pillow because I wouldn't let go of it! I would cry if I didn't have my pillow for one second. I would take it shopping, to the park, to the homes of friends....EVERYWHERE! Since I didn't let my mom wash it, it was dirty, and stinky, and full of germs.............so one day, I woke up in the morning, and my pillow was GONE! Ohhhhh how I cried that day! My mom told me she threw the pillow away, and the garbage man came with his truck and took it away.......and I would never see it again. Poor me. I cried and cried and cried..........but hey, it put an end to my bad habit! Guess it was worth the torture. I don't remember this since I was just 2 or 3 at the time, but this is what my mom told me. How dumb children can be!

(Maybe you can throw your nails away to get rid of the habit? NOT! ) LOL
