Teething at 4 months? Say it ain't so!

Just when I get to a point in my breastfeeding where it is comfortable, as opposed to sitting in a rocking chair and digging my fingers in so hard that I removed varnish from the armrest due to pain, Avah is teething! Now, I have to ask, will this start to hurt again? Please God, I tolerated agony that rivaled pain from the c-section. Maybe give a girl a break?
