Hello ? I don't know how to be anymore. I really want to finish breastfeeding because the baby doesn't sleep through the night without me and now he has teeth that are cutting him up and he chews on them until it bleeds. On the other hand, I have a stone in my chest and guilt won't let go... As soon as I imagine that he will no longer need me, tears well up.
