The growing popularity of ear-stretching (for girls and boys) has created a problem for parents. Since kids can begin stretching from any sized hole in their ears (a standard pierced ear can be stretched using tiny stretchers in increasing sizes), how far they go becomes a concern of parents. It’s one thing to see a small stretcher in a child’s ears, but another sight altogether to see them sporting 00G or a 1/2 inch sized tunnel.
Similar to a parent trying to stop a child from getting pierced (or worse, piercing themselves), stretching becomes a problem because unless you are with the child constantly, there are always opportunities to stretch. Rather than say no to stretching outright, it may be a better solution to be a part of the process, and if necessary, allowing your son or daughter to stretch, while agreeing to a pre-set limit on how far they can go. Setting a limit on size (beyond 00G is irreversible) helps keep everything out in the open and most kids will see it as a compromise on your part as a parent, an honor the agreement. Measuring the body jewelry they are wearing will encourage compliance with the limitations agreed upon (there are parents that have gauge calipers for this). At least if you are a part of the process you can monitor it. Make sure your child goes safe and slow (no more than one size every 3 weeks) and that they stay under 00G, so if/when they change their minds and take them out it is still reversible.
