There has to be a better way

There has to be a better way to say it?

I was recently enjoying a great day at the local pool when I spotted this massive, confronting sign – kinda killed the fun for me!

For starters it isn’t worded correctly – the top message implies that the parents weren’t properly supervised!
I can get their frustration but why insult parents who are responsible?
How would this make the parent of drowning victim feel?
Is an irresponsible parent going to pay any attention to it anyway?
Is there a much more positive and effective way to do this like:

“Relax by knowing your kids are safe”,
“We need your help to ensure your kids have a fun, safe day”
“Isn’t it great watching every fun moment your kids are having”,
“Your kids love it when you watch everything they are doing”,
“Thanks for being such a great, responsible parent, you are welcome here any time”
“Your kids are having a great time – please don’t miss any of it”
“Thanks for watching your kids have fun – we admire and respect that. Please come back soon, you may our work easy and enjoyable”

Love to hear your thoughts………….
