My daughter will be 1 year old in Feburary. I am very excited to through her a party. I also have a son who will be celebrating his third birthday in March but the last 2 birthdays his grandparents (my in-laws) showed up with their own booze. How do I tell them i want an alcohol free birthdays this year. It soooo imbarasing when they can’t handle them selves around company. It’s a child birthday party for crying out loud. I wish they would leave the booze at home. It’s not like my husband and I don’t drink but there is a time and place for it. They are great people so I don’t want to hurt their feelings. Any advice out there?
