See, that's just wrong. The only time someone should intervene is if someone is going to get hurt (verbal, mental, physical - whatever). That wasn't the case and he shouldn't have been a tool about it. Sounds like he needs to see his supervisor for some customer service training. Lifeguard or not, he's not there to parent anyone. He's just there to make sure no one gets hurt or drowns, make sure pool rules are followed, etc. Parenting is certainly not in his job description.
Now that I think more about it, I really think I would have noted his name and reported him. Not to be mean towards him, but he really needs to know that its not okay to interfere with parenting.
Some kids just need a bit more coaxing from mom/dad before they're ready for something. And I truly believe that sometimes, its
not okay to drop the topic and come back later. You know your kids best, and you know when its time to drop the subject and when its okay to keep pressing.
If she was doubled over in hysterics and you were yelling at her trying to force her in, sure, he could intervene then. But not trying to talk her into something.
Okay, someone needs to take this soap box away from me.
My fingers don't know when to stop.
DS asked repeatedly to visit the pirate pool this year, but he loved the slide at CSR, so it was a good trade off.
