Query: The one thing our baby didn't chew on...

We were disappointed in this product. My baby was 8 months at the time of purchase, liked paci's & chewing on pretty much anything she could get her hands on. She chewed on this 30 seconds & tossed it. I continued to re-introduce it to her over a couple days and she just had no interest. I tried an organic toothpaste she likes on the "toothbrush" which helped her chew it for a minute; however, even with guidance, the bristles did not wrap around teeth/gums in order to work properly. For this reason, the "first toothbrush" is lucky to get 2 stars. I am sure it helps brush other children's teeth when a child will chew it long enough, otherwise, I recommend just using a washcloth or the finger toothbrush.
