Yeah in my day no protective wear was ever done. Not for bike riding or skate boarding or anything. But I rather be prepared better safe than sorry.
Just like Hockey or construction sites or any where else that matters. It hardly ever happens anyone gets hit in the head but it does happen so why take the chance?

Thanks Mamagato I will do as you say.
@ Krigaren (damn that is a long name) I know what you mean. I never thought of him moving his head so will do that as well.
@ Old Andy I never thought of getting him a new one every 18 months. Yeah he is growing very fast.
Thanks all for the help, I really appreciate it and when we go today, I will use your advice. Thank you again.
