I think it is good to not judge other parents when possible. I think, y'know, the backpack full of books lunges parent maybe.
Last year my daughter (age 4) had this ... let's say I am a pre-team gym parent and proud of her but I was not a gymnast and I can see my daughter doing other things if she wants to.
Last year my daughter was in 3 gymnastics classes a week IIRC. Since she was in the preschool division and these classes were 45 minutes, packing up both children to attend them was really a hassle, in a labor of love kind of way. Her choice.
Anyway one of my daughter's tendencies as a four year old was to not want to do things she was not particularly good at. I emphasized hard work instead of outcome to hopefully put that more back on track. For what they were doing in that preschool class, she could easily have been on the playground monkey bars for free and just taken the other two classes a week.
She was always asking to go to gym, was talking about how she was going to be on team one day, etc. Then she would get to class, one class in particular where the rest of the children were younger, and she would SOOOO slack off, I mean absolutely wasn't trying and when the coach's back was turned she would do nothing. But didn't want to quit. I am all for letting kids do classes for fun but she was already doing 2 other preschool gymnastics classes a week. I went to the owner finally and asked could the coach hold her accountable please because I don't care for spending money to have bad habits reinforced (not those words but that was my concern). Owner said she thought DD would be discouraged from the sport if she was pushed. This is not true but owner / HC doesn't live with her and know her like I do. DD will perform to the level she is expected to perform to, to a point, with the same level of satisfaction ... probably more from being pushed because she accomplishes more. And now after a year of developmental classes she is starting to internalize this, loves gymnastics more than ever, and we don't have the same kind of issues. She practices on her own -- last year if a coach told her to do something for homework, she would tell me "my teachers don't know what I do at home." She doesn't always give her workouts at the gym 100% but she's working hard.
That's not me pushing my daughter last year but it might look like it from outside the relationship. If you didn't know that this is my daughter's third preschool class of the week, that she's the one wanting to be there not me, you don't know her general developmental level, etc. you could say "how horrible this mom wants to push her 4 year old daughter in gymnastics." When rather, she and I must navigate this together, along with the family budget etc.
So then I ended up having to work like the dickens to get her into developmental classes. DD tells me last summer she wants to take 9 gymnastics classes a week. Wants to be on team. I hoped summer swim team might redirect her interests to something more typically suited to super tall women with big feet. Nope, she got more passionate over the summer. She wants to do gymnastics on vacation at the river. At that point she's only taken rec classes and is very middle of the pack. She's in the top 10% maybe in the population athletically, but of kids taking rec classes probably right in the middle. She's not going to be picked for developmental classes if I do nothing. And at her rate of growth she really needs very frequent conditioning to keep up with herself.
Which is a whole other story but I did get her into developmental classes (which some people might think was me pushing her ... where I see it as simply trying to spend money in a way that advances my daughter's goals most effectively) and she is thriving, still begging for more hours than she gets, and she is still super motivated, and soon, hopefully, she'll be snuggled into a situation where she will have all the hours she wants and she'll be getting the level of training that matches her enthusiasm and goals, and I can sit back and NOT WATCH! Oh, I'll watch some. I just dream of the day she's 8 or 9 and maybe she can just bike or take the bus or carpool to nice 3 hour team practices ...
So ... it's hard to know the backstory of everything we see.
