No. I didn't even use mine really with the last one (or two?). I know at one point it was in a minor flood in our laundry room and could not be used anymore. Honestly though I wasn't a huge fan of using it for nursing purposes.
Yup! my toddler uses it as a pillow as well. also when he is a bit older and less gogogogogo i suspect he will love to use it to prop himself up and get comfy watching his favorite shows. I've also used it for extra back support myself on the couch, it isn't just for kids, its comfy!
