  • I suck my thumb too... 17 years old. I think it's normal as there are plenty of people who still do it, but I have teeth problems and I'm always worried that I'm going to end up sucking my thumb in front of someone without realising, as with a lot of bad habits I don't really notice I'm dong it! I wear woollen gloves when I am watching tv or in bed, as this is when I tend to suck my thumb. Apparently it only takes 21 days to give up a habit, so I'm going to keep trying (although I've been trying since I was 10!). Good luck!
