Sounds worse than it is. At the beach yesterday, was a quiet bit. I was on a blanket with ds2 (who refused to set foot on the sand) ds1 was having fun running up and down the beach and just in the edge of the sea paddling/dipping his toes , he wouldn't go in, far too cold and he's a wuss.
It occurred to me was that terribly irresponsible, could see him at all times.
I am usually was OTT with safety, trying to relax a bit and allow him a bit of freedom.
