My DD is 8 months old, has 4 teeth. She's still working on the top two, they broke through the gums at least, it was sad, she was not happy. When did you start brushing your lo's teeth and what toothpaste do you recommend? I'm a little concerned about how much toothpaste she'll swallow. Once you started brushing lo's teeth, did you do it in the morning and at night, or just at night?
