Thinking of using adult diapers for after birth

I’ve heard a bunch of people say that adult diapers were way better after they gave birth than the hospital pads.... I’m kind of wanting to try them but I’m so embarrassed about going to buy them lol it feels like your first time buying pads or tampons. 👀🤦‍♀️😳 thinking of going through a Walmart self check out so I don’t have to face anyone 😂
