One of the fathers of one of the better kids raved about how my son did the game before at goalie and how his diving save was something you can't teach really. He said he was telling his wife the whole way home from the game.
That's a great feeling when other parents talk to you about your kid. If another parent hadn't done that for me when my son was 8, I may not have made it a habit myself.
Make sure you occasionally brag about YOUR kid (in front of them) after getting in that other habit. My son exploded at me a while back after he was the best player in a game (I was coach) and was hyping the other kids games to their parents in front of them instead of him. He was so mad, lol. He was right.
My son's playing days are over, and since I was never a coach but rather just one of the countless other parents all bragging on their kid, I always told him to let his game do the talking. I once hinted to his travel ball coach that I thought with my son's speed and being a lefty batter that he was a 'prototypical' leadoff hitter. To the coach's credit, he took in what I said and kept him where he was, lower in the lineup the rest of the season.
I witnessed a lot of parents not only lobbying for their kid but also against teammates in the hopes that it would improve their own kid's situation. TBH, my son never cared much about praise; he 'got' sports, always worked hard and always played with joy. That was all the reward he ever wanted, and if you've read my stuff, you know he was rewarded a LOT. It has even puzzled me how nonchalantly he reacted when he earned awards:
male athlete of the year in 8th grade,
2nd team all county as a junior and 1st team all county as a senior in HS,
offensive MVP in the Brooks Robinson All-Star High School Classic (played at Camden Yards),
conference rookie of the year as a freshman in college,
first team all-conference every year he played,
conference co-player of the year as a junior,
his college's male athlete of the year his senior year.
TBH, I love talking up my boy, but he doesn't really care to hear about it, and as I said in my post in this thread about his final career statistics, it's an embarrassment of riches, so i try not to talk about it. Unless the right situation presents itself.
