Any suggestions for thicker nursing pillows? I used two boppy's stacked with my first two. Those have both since been handed down and no where to be found. I'm looking for a new pillow, but don't want to have to buy two just to be tall enough without me having to be hunched over to nurse. The only one that looks like it might be tall is the Born Free Bliss nursing pillow. Has anyone used it before and know if it's a good one?
