Jack doesn't yet have teeth. They're on their way but haven't made an appearance yet. Jack does, however, have a toothbrush. You see, our Little Man is very concerned with proper tooth and gum care - mostly gum care right now. He loves, LOVES to have his gums brushed every night. He actually enjoys chewing on the toothbrush more than anything. It's become part of our nightly bedtime routine. He could squeak away on his toothbrush forever!
