My Sugar Baby( 5.5 years old) does GREAT with her Sonicare toothbrush, but my Curri
(7 months old) is a little harder to convince
I am currently brushing her teeth in short bursts with baked chicken mashed into the bristles (for now) to get her to tolerate the vibration a bit more. We are up to about 25 seconds with Curri and a full 2 minute cycle with Sugar is a piece of cake.
Good luck!
