The teeth didn't affect bf with either my son or daughter. There were times it was a little uncomfortable when the teeth rested on the breast, but if I unlatched them and relatched again, the discomfort went away. My daughter did bite me once and I just said no and took her off. She never did it again.
When I e-mailed Dr. Newman about decreasing the dom, he said he would wait until my daughter was at least a year and was solidly on solid foods. She is 14 months and I still haven't decreased. I am planning on weaning by 16-18 months, but haven't made a plan on how I will decrease the dom. I will probably e-mail Dr. Newman to see what he suggests.
