Girls, hello everyone! I have such a problem, my son's teeth are erupting, they've already come out a bit, so he constantly bites when he sucks on the breast, it hurts, I can't even imagine what will happen next, I'm already scared, I don't even want to hold him, I'm afraid that his breasts hurt. What should I do??!!! ? Every time I think about how he will bite when there are more coming out, I want to cry ?
