Wine and breastfeeding

With the holidays coming up I want to make sure I’m consuming alcohol safely while breastfeeding. I would only be having a glass of wine with dinner. To my understanding there’s no need to pump and dump. And if I’m “safe to drive I’m safe to nurse” correct ? Is there a need to wait a certain amount of time after having a glass to nurse? I assume the longer you wait after having a drink the better. I was considering buying the test strips but I’ve heard they’re not that reliable. I just want to make sure it’s safe for baby but i also want to enjoy a glass or two of wine with my family!
