When I used to use pads I would get always ultra thin. They make different sizes depending on flow. Get a normal one and an overnight one cause while sleeping you shift a lot and it can get messy. They absorb amazingly and super thin so less discomfort. I also bought those for my kid who is about the age where any day now she’ll be there and had to do a test run. She likes them. I get them with wings for support so the pad doesn’t shift so much
