Other posters have said this, and I'm going to reiterate it- these girls NEED their teammates.
This times 1000. Trust me your jealousy will at some point become your child’s jealousy over time. I watched a crazy gym dad slowly ruin my child’s 7 year best friendship due to his constant comparing, competitiveness, blaming perceived coach favoritism. The truth was very far from what he saw, his child was suffering under his pressure and comparison but she wanted to please dad so it got ugly. It was heartbreaking and the whole situation sucked. They changed gyms, the girls no longer speak.
The two girls that were inseparable for YEARS are no longer friends. His attitude crossed over. The two would have benefited so much from SUPPORTING each others journey rather than turning it into a constant competition everyday. Kids take direction from your attitudes and it will become theirs if you are not careful. As levels get higher these girls need each other’s support to survive.
