My Sister in law just tried to feed my baby red wine last night at our CNY reunion dinner. She said it's custom to feed 1 month old baby a little wine. I think she's nuts. Is this true?

Totally insane! Im sorry but no she shouldn't do that. Learn how to respect that not all babies are the same. Especially if its our own, we have to protect our own babies from harm... she can do that to hers if she wants...
