This answer is very similar to the one above. Let’s face it. We all have a crutch that helps us get through the tough times. Some people rely on faith, others on food and some on other addictions.
So, it should come as no surprise to you that our children have their own little “fixes” to get them through the tough times. One of the biggest of these is thumb-sucking or finger-sucking, with or without the use of a “blankie.” I would never dare ban the coveted “blankie.” In fact, I know several adults who still sleep with theirs! I sucked my thumb as a child, and oh, the relief was amazing! But again, at some point certain addictions have to end before they have damaging consequences.

Generally it is safe to let your kids suck away until age four. Before age four, you may notice the effects of sucking on their front teeth. What you will likely see is that your child’s front teeth are “bucked out” and perfectly fit the offending thumb like a key in a lock. Prior to age four, if the child stops, the teeth will usually drift back into their normal position. After age four, however, the effects become more permanent and may also affect the path of eruption of the permanent teeth and shape of the palate (roof of the mouth). This can result in your child’s permanent teeth also appearing “bucked,” crowded, spaced or some combination of these. And, you guessed it, an expensive trip to the orthodontist!

I need to address a widespread problem regarding bottles and sippy-cups. NEVER let your infant or toddler fall asleep with a bottle of milk or juice. I know from personal experience that lack of sleep can cause us to take desperate measures. One of these measures is propping or allowing a child to have a sippy-cup or bottle of milk or juice to help them fall asleep. This is the number one cause of severe tooth decay in children and its effects can be devastating. This situation is called “baby-bottle tooth decay” or “bottle rot.”

Once the baby/child falls asleep, the milk and juice pools in the mouth and those cavity-causing bacteria commence their attack. It can decay a child’s teeth so quickly and so severely, that that the child can actually end up losing all or most of their baby teeth. This is especially troubling considering they don’t start getting their first adult teeth until around age six or seven!

 
This loss of teeth can lead to many disheartening situations, such as the child having to wear a partial or complete denture just to be able to eat. This is a very tough ordeal for a child to have to go through on many levels, including functionally, socially and psychologically. Not to mention the many extra trips to the dentist the child will have to endure throughout their childhood. So please try to remember to reserve those cups and bottles for mealtime only. You can see for yourself the devastating consequences that it can have.
