I didn't eat any 'special' diet while BF Jonah. I did monitor my liquid intake, making sure to drink things besides water. I went with Gatorade, and would usually drink half of my daily intake of fluid in the form of juice/gatorade, and the other half water.

What I found to be the most, invaluable, life saving, can't thank 'em enough support was Le Leche League. For me, nothing I was trying was working. I was cracked, bleeding, raw, on pain meds, etc. Nothing worked but having one of their leaders show me the proper latching. (Even if you think you are doing it right...I would call them).

Jonah had a frenulum issue, and it was snipped at 6 weeks, maybe? And, we did suck exercises, as he has a high palette (sic). Both helped tremendously. Also, proper support in the form of a nursing pillow made a big difference. The Boppy was worthless to me- just not enough support.

I went on to BF Jonah until he was 2.5 years of age, and can count on one hand the biting or gumming instances. All a matter of finding your rhythem (LOL, I cannot spell tonight).

Good luck.
