Ummm am I supposed to be brushing your teeth?

Not sure if I'm supposed to be brushing Isla's teeth or not. No one told me what was the right time to start dental Hygiene but I feel like once you actually have teeth then you should start cleaning them right? Anyway, I bought teeny tooth brush and some banana tooth paste. Isla is obsessed with it and thinks it's hilarious to brush her teeth. I think it's hilarious the faces she makes. We all win.
