Query: Baby toothbrush

To develop a love for brushing his teeth early, I picked this one based on the visual of the toothbrush part. My 4-month old son loves it. He's been using it since month 1, and we just use the dishwasher to keep it clean (in the bottle parts box we have for the dishwasher). He sucks on the bristles which cleans his tongue, and then he chews on the bristles to massage his gums. Now that he is beginning to teethe the toothbrush is even more fun with him. Hopefully he will continue to love brushing his teeth as he starts getting teeth.
