I discovered the diva cup a couple years ago and it's changed my life. However, it is no good to me in my post-partum situation.
Enter: cloth pads! I bought one (ONE!) at the coop for something ridiculous like $10 or $15. So my doula mercifully sent me a bunch of links to different patterns and ideas. After looking at those, I went to the fabric store and spent $13 on cotton batting, cotton flannel, some nylon, and some snaps. I've made 3 large post-partum pads with 8 inserts, and 4 regular liners with something like 10 inserts. They're adorable, soft, eco-friendly, and cost a fraction of what you would pay for pads from "Party in your Pants".
Ruby loves the colorful inserts so much, she's been calling them her "lollipops" or her "snacks". Which I find mildly disturbing.
