Depends what you mean by that...
My dd is 9. When I bring my dd to a comp, of course I help her make sure she is fully ready. Hair neat and in the required style, warm up jacket and pants over comp leo, gym bag stocked with hair supplies, extra leo, drinks, snacks,
grips, etc. We may stop in at the bathroom when we get there if touch ups are needed. I don't zip her up, just like I don't dress her in any of her other clothes. We get there with enough time so don't need to be 'faster'.
Once I've handed her over to her coach though, I'm done. If she did come in to awards with open jacket, I might cringe internally but that's it.
I do put a fair amount of emphasis on self-sufficiency in parenting my kids though so mostly I'm just checking up. Went through a few years of cringe-worthy outfits and giving gentle suggestion (" honey, red and pink don't really look nice together" lol) to get to this point. Ah well, at 3 and 4 years it's just funny when they have clearly dressed themselves.
