I have no doubt that #2 was a thumb sucker in-utero. For the moment she made her appearance, she started sucking her fingers. She was a very calm baby, rarely complaining. She often sucked her thumb, and I never saw a reason to stop this self-soothing practice...
Until recently. She will be two in two months, and the thumb sucking hasn't decreased in frequency nor duration (apparently most thumb-suckers do slow down around 12 months). And we have noticed that her upper central incisors, especially the left one (as she exclusively sucks her left thumb) were starting to angle upwards.
At a recent dental appointment, I asked my dentist for suggestions, and whether or not there would be any permanent damage...He suggested a bad-tasting nail polish, and said that to avoid permanent damage, she would have to stop by age four.
So I researched bad-tasting nail-polish geared at thumb-suckers, and found one that was highly rated. However, it wasn't recommended under age 3. Not because it was toxic , but because "taste buds are not yet fully developed under age two, and toddlers may actually enjoy the taste".
In the end, I decided to order the product, but wait until I tried some behavioral modifications...
First, I ran my daughter's index finger along her teeth so that she could feel her incisors. I explained the her teeth would be "crooked" if she sucked her thumb. Much help that did! #2 is in an "opposite" phase at the moment. So not only does she continue to suck her thumb, she goes so more vigorously, and sometimes sucks both simultaneously, with a sly smile on her face and a twinkle in her eye.
Next, I tried to keep her hands busy...and even taught to use her right hand play with her thumb instead is sucking it. That lasted less than a minute!
I tried to observe her thumb sucking... perhaps if I discovered the trigger, I could avoid the need for thumb sucking. While she often sucks herself to sleep for a few minutes, she quickly removes her thumb and she sleeps well without additional thumb sucking. However, during the day, she often resorts to thumb sucking when she is upset. Unfortunately this happens very often. For instance, last week we were out for a walk in sub-zero weather. While in the stroller, she decided to remove her hat, mittens, and her boots. When I tried to explain the need for those items, she says "NOOO", cried, and sucked her thumb. She is very contrary at the moment, and this type of incident occurs at least a dozen times a day...
After a few weeks of unsuccessful behavioral modification, I decided to try the nail polish. At first I painted just a small portion of her left nail. It made absolutely no difference! Next, I painted her entire nail. I explained to her that it would be "yucky" and that she should not suck her thumb. So, of course, she sucked her thumb. She made a funny face, and her eyes watered. She sucked her thumb a little less for a few minutes. But within a few hours, she was back at it, and in fact sucking more than ever.
After a few re-applications, I gave up in the nail-polish. The directions said to re-apply every 2 days, but how could I when the polish seemed to wear off after only a few hours...
Finally, my daughter found a solution: she asked me for a bandage, and applied it to her mouth:
A few minutes later, she had removed it.
Then, we tried some fun-coloured gloves:
Also short-lived.
I offered her a pacifier with Oscar the Grouch on it. She seemed interested for about half a day, then she wanted nothing to do with it!
In the end, perhaps she will eventually give up this habit if I simply continue to insist on her stopping???
