I cannot believe the fear mongering on here!
I come from a liberal state where drinking is allowed as long as the parents are there. So, yes, my kids have had sips of my beer, and anything else alcoholic I might be sipping on. My goal for my kids + alcohol is to take the mystery and fascination with it away. If it is something that is not "forbidden", they will likely not over indulge. Same way I was raised.
I understand Florida doesn't hold the same laws, but at 19, I would still offer my kid a sip, in Florida, if he asked..
