More teeth

The bottom teeth pushed their way through either today or yesterday. Max doesn't even seem bothered by them. I bought my little T-Rex his first tooth brush yesterday with the kind of toothpaste that is okay if it is swallowed. Do any of you moms out there have any teeth brushing tips?

p.s. I love the picture above, he is 'flying' with his daddy. He looks like such a boy with the snot bubble coming out of his nose...sorry, I had to share.
