Getting past the biting?

[ZooCrew10]

How do you all get past the biting stage to nurse extended? My little one really chomps down and then grinds, and thinks it's funny when it makes me yell! It really hurts! I've had to reduce BF to when she's barely awake, like late at night or first thing in the morning (when we snuggle) or she really bites me hard. Any advice??
