It's ok. The bite blocker tail part is a little big for our little guy's mouth and while he really likes carrying it around and chewing on it for sensory stimulus, it's not quite the magic bullet for our toothbrushing issues that we were hoping for. I really wanted it to work for us, as it came highly recommended by the mama dentist, and we're running out of ideas. I'm hoping it will still come in handy when he becomes less hostile to toothbrush time.
