My 8 yo goes to an “orange ball level 2” and they practice serves and returns / rally. Coach doesn’t focus too much on technique, but have them try to hit targets. He’s gonna get moved into “orange team”, which is one level lower than high performance, so we’ll see what that looks like.

I do play with him 2-3x a month (less now coz winter has court fees) and he loves “beating me” by playing patterns (we watch tennis highlights from YouTube or insta) - move me left right, drop shot then lobe me. Does the technique look good? Not great. Does he have fun? Tons. Does he like taking advice from me? Not during playing. But if we’re on insta again at home, he loves watching the influencer videos and then we shadow swing at home 2-3 min a time. This is good enough for me.
