My mother just brought me some pads and she only had to buy them for about a year as I then got a job and had to buy my own. She never gave me the talk or anything, I think I picked up most of it from magazines etc.

My eldest daughter I really can't remember what talk we had, I just kept her supplied with what she wanted till she went off to UNI 5 hours away.

My youngest has been the most difficult. I've talked to her numerous times but because she has an intellectual delay and is on the spectrum it never sinks in. Her first period I actually had to place the pad (I got the ones with wings for added grip) onto her panties and show her how to do it for the first few days. We are over a year in and she had expensive pads, cheap pads, tampons, panty liners and yet every month I get panties covered in blood still found in the wash.

Honestly just talk to your daughter, she probably knows it all anyway but just incase. Maybe take her shopping and let her decide what ones she'd like. She may have friends that already are using them. Also it will depend on her flow, overnight ones for nights but days may be heavy or medium or a mixture. This will all depend on your budget too as in Australia they are pretty expensive to buy, so if cost is a factor work out which ones you can afford and let you daughter pick from them.
