Your wife seems wise. I would suggest you learn from her and just let it roll off.
If that's not enough, consider:
Gymnastics is a tough and expensive sport. It's tough and expensive for the families and for the gyms. Gyms have all that lovely overhead of insurance, rent (or payment if they buy the land), upkeep, equipment, staff, etc etc etc etc. Not all gyms make it through the first year or two.
It takes a lot - in this case rec kids, parent nights out, open gym, and yes, even xcel and JO kids - to help pay the bills and keep a gym in business so that they can train their upcoming slate of AmazeBalls. So if you happen to be a parent of one of those special tops/hopes/elite kids who's lucky/blessed enough to have the "complete package" including but not limited to:
interest, talent, solid financial support, familial support, mental toughness, able bodied, good general health, flexibility, emotional support, live in an area with access to training, good positive coaches, supportive gym owner(s), access to the best medical/rehab/nutrition/etc
and without:
mentally/physically/emotionally abusive coaching, constant coaching changes, instability in the family structure, unstable income, repetitive or serious injury (which even when healed can result in a serious growth spurt that changes everything), a bad case of the twisties, or mental blocks, death in the family that requires a change, previously unknown physical illness or weaknesses, or any other number of difficult but possible issues that can derail one's hopes and dreams
If your kid just happens to be one of the lucky/blessed kids who struck gold or at the very least silver on this list of pluses and minuses, or if they are lucky enough to minimize or compensate for any that did affect them, maybe you could let things like this go and just be thankful that these other people are in your gym helping keep it financially solvent. Most kids don't have that complete package and weren't tapped for extra attention. Because extra attention (whether or not it shows in actual hours in the gym or in just special time apart) does help. All of these things have an impact. And your kid is lucky. For her sake, I hope her luck holds. So just consider yourself lucky/blessed too, say thank you to anyone who says your girl is "too good", and move on. This is her thing anyway, not yours.
