I shall tell you. It's a stroke of simple brilliance coming from a mom who wanted her baby comfortable and happy; herself and husband well rested. How did we ever live without WubbaNubs? I do not know. I only understand how grateful so many of us are to have them now.
Latex-free and made from medical grade silicone, The WubbaNub can be machine washed in a lingerie or mesh bag. Beans are sewn into a separate safety sack within the plush toy. There are several plush animals to choose from. Tons of Love in every Nub!
