My son started over the last day or so pulling back on the nipple while it's still attached and he's still sucking on it. Needless to say, it hurts and my nipples seem to be paying the price. What would make him do this? Aside from unlatching him or pumping & feeding a bottle what else can I do to curb this behavior? I've tried holding his head tighter and it just makes him mad.
Any help is appreciated.
