I’ve used period pants for coming up to 4 years now. Originally I researched because, like pp, I have a dd with SN, who wouldn’t be able manage pads independently. I wanted to make sure that whatever I proposed for her would actually work, so trialled them myself.
I have very heavy periods (overflowing mooncup every hour) with lots of clots. Initially I used thinx (before they were annoyingly woke). They work. I change at lunchtimes (easy for me to do so) or use a reusable pad n the morning and remove at lunchtime if not able to change).
No rinsing, I just put in the washing machine. I think I spent £200ish (inc customs) 4 years ago, and they’re still going strong.
I have also cheeky wipes pants (MUCH cheaper) and they cope well too.
Dd1 uses thinx, no problems and has kept her independent in the bathroom (SN), and dd2 wants to try too (anytime now)
