Congratulations! Fantastic post.
Thank you for mentioning your child, I relate to that too.
Wine is given to children so young here in Italy. I remember my nieces 8th birthday when both she and her younger brother (about 5) were given a small glass of prosecco to celebrate. The younger brother started saying "I feel funny, what is happening?" and all of the adults were laughing. I was horrified.
ALL of my children's Italian relatives have been given explicit instructions to NEVER give my children alcohol. Not their father, aunts, uncles, cousins, grandparents, no one. I pray with all the might I can that they will never touch alcohol but I know the day will come that they are curious or want to fit in or whatever.
The best thing we can do is be good examples.
And you LG are doing just that. Amazing.
