well, there is a big difference in between "wanting to know what is going on" in your kid's life and giving kids no space of their own aka not trusting your little one to be able to handle their own things in their own way or being too afraid of anything going "wrong" for them. independence and maturity are two sides of the same thing.
to put it another way: how on earth can one expext one's kids to gain "lilfe experience" if everything they get to experience is designed and monitored and carefully planned out in advance as far as possible? life is not like this.
The OP didn't say anything about wanting to micro-manage their kid's life to the point of crippling dependence. Nor did I. Nor are most parents out there. No one is asking for permission to bombard the coach with questions ever meet, every score, every skill, every toe point. While some parents need to understand the difference, yes, but they are not the majority. They can be dealt with. And their kids are likely to burn out before the coach has to deal with them for too long anyway. I think what the OP and others are saying is that there is ZERO harm in wanting to know SOME things SOME times. Simply feeling like you have a partnership with your child's coach in something that they spend practically their whole life doing is not bad, or hindering their development as either a person or an athlete. The parent is an ally, or can be, if they are not made to feel like they should have zero part of the process besides dishing out cash. It's all about balance.
To the poster that said it's not the coach's job to educate the parents about the technicality of the sport - I agree mostly. Some parents want to know nothing, some want to know more, but as long as their gymnast understands the technicality of it, then the coach is doing their job. But if the coach shares nothing or next to nothing about the process, and their child is young or new to the sport, then a parent can't make informed decision as to whether or not the coach is doing their job and their kid is ok. For example, I know nothing about my other child's sport. We lingered for far too long at a facility that was not benefiting her well-being or her progress because I just didn't have enough information to make an informed decision. She is thriving in a new environment now, and I feel much more trust, because they don't make me feel like a Crazy Train for checking in and asking when I don't know, or bringing something (good or bad) to their attention. Another example: just because I want to understand and be somewhat involved in my kid's education doesn't mean I think I am their teacher, or I'm trying overthrow the principal. It doesn't mean that I don't trust their school, or that my kids will grow into adults that can't think for themselves, or that they are going to be cripplingly dependent on my wisdom forever. If my kids attended a school that made me feel like I should never inquire about anything (like many gyms) because they are omnipotent, we'd find a new school.
As kids get older, they can and should take more ownership over ALL aspects of their lives. It seems it's only gymnastics, though, that expects them to have the cognitive and emotional ability to do so the day they walk into the gym, just because they are physically capable of very difficult things.
