Yes!
Now I'm not saying that this is actually what
@Jenniturtle is doing to her kiddo, but I will tell you that parental attitudes can be a HUGE setback for kids in dealing with mental blocks in general.
The worst thing for a kid is to get picked up from a private and hit with a barrage of:
"Did you throw it?"
"Why not?!"
"What is the deal?!"
"Maybe it's time for a new coach!"
"If you throw it by next month, I'll get you those Uggs/that phone/whatever!"
"Ugh. Seriously. If you don't throw it by _____, we're going to a new coach."
"If you don't throw it by ______, we're done with cheer because I'm not wasting my money for you sit out."
"If you don't throw it, you're not gonna make Level 3 and I am NOT wasting my money for you to be Y2 again this year."
"Insert Other Kid Here just got her _______, I can't believe you're still not throwing your _____. She's going to make Level ___ before you."
None of the above are going to help your child unblock on a skill any faster. If anything, it will keep them blocked, make them hate cheer, and resent you.
A simple "How did your private go today?" is JUST fine.
