Drinking in hospital

So my fiancé’s two sisters came to visit today and we got to talking about birth/labor as I am due any day now....they both mentioned that they drank IN the hospital after giving birth. One of them said she drank a couple glasses of wine in the recovery room and the other said she was literally taking shots with the nurses (she’d been there for a week as an extended stay due to complications with baby)....they’re both from bigger cities and acted like this is normal and allowed. I thought back to when I had ordered my hospital bag on Amazon and saw in the reviews women saying the bag had a compartment they used to sneak champagne in the hospital after having baby....so now I’m just curious, is this like a common thing? Lol no judgement, I enjoy drinking occasionally and I’m looking forward to having a few drinks although I’m not like pressed on getting drunk right after my baby comes....but after not drinking for 9 months I would be afraid one drink after giving birth would have me pretty damn tipsy so for that alone I’d fear drinking in the hospital lol. Thoughts and opinions?
