Query: Life Changing!!

This product changed our life! In the beginning the Wub-a-nub is great because it acts as a weight on the baby's chest so that they do not lose it as often. You can even wrap a swaddle around it to ensure that it stays put. As they get older, the stuffed animal is something that they can feel for and find in the dark. My little girl loves her "wub" and so do her Mom and Dad!
