Postpartum bleeding

Sarli
This is my third pregnancy and baby, so I feel confident knowing what to expect. (I also know nothing goes as planned! Lol!)
For my first two I used the biggest pads possible (more like a small child's matress) and still leaked. I also used the "puppy pads" just to help easier clean up. 
This time around someone told me about the adult diapers, and always has some that look relatively comfortable and efficient. 
I was wondering if anyone had tried them? Or has any thoughts about adult diapers for post partum bleeding.  Thanks.
