i am not a parent.
but i was teased mercilessly for a variety of things in school and felt self conscious for many, many years thru my adult life.
i feel bad because i know my parents agonized that this was something that they could not change or fix and they always continued to encourage me and in spite of not a lot of money did their best to make me feel more comfortable with my appearance among my peers.
i also know that with the background my parents came from, even though they may not have measured up all the time in the looks, height, weight department...it definitely was not a priority.
i do know my parents were proud of me for a lot of reasons, but felt no reason to brag...you just didn't do that...you also didn't tease or make fun of someone's appearance of condition either. that was a good thing. everyone is an individual with their own "beauty" and value.
the only down side, i can admit, i never developed that "i can have it all" attitude
...no matter how much confidence you instill in someone...society and employers sometimes DO act more kindly to the aesthetically gifted...but if they learn the own personal gifts...in spite of the almost guaranteed bumps along the way....they can do just fine.
