I think the key thing Dear, is try not to stress too much (I know, easier said then done). I am a La Leche Leader: Most of our Leaders are great. You might have had the misfortune of hooking up with one (or maybe even several) who are not. It happens.
You sound like you are trying everything that you should. Tenderness in the breasts (depending on how far along you are) can definitely be a sign that your milk production for this baby might be a lot higher. As to thyroid, keep it monitored. I have low thyroid (take levothyroxin) and thyroid plays an important role in milk production. These natural approaches might help too. I have had woman I have helped have success with these:
Eat oats. Eat oatmeal, bake and eat oatmeal cookies--be creative. eat at least one cup of oats every day, split into two or more eating sessions. Drink plenty of water when you eat the oats. Oats are a galactogogue (something that increases breastmilk production) and are very healthy for your digestive tract as well.
Take fenugreek capsules. Fenugreek is an herb that helps to boost breast milk production. It has a "maple effect"--women who take fenugreek in large enough doses to increase supply find that they exude a maple-syrup scent. Start with 1 capsule per day for a few days, increase to 3 capsules per day (1 capsule three times a day), and then go to 2 capsules, three times a day, for as long as you need your milk supply to be boosted. Drink eight to sixteen ounces of water with each batch of fenugreek pills.
Drink half a dark beer up to three nights a week. This may seem counterproductive, but many experts recommend drinking half (6 ounces) of a dark
beer like Guinness, to help stimulate breast milk production (my Husband's family is from Ireland and generations of Irish women swear by this. My Sisters-in-law all do this and so do I. It really helps with "letdown," i.e, milk in the tissues of the breast being released).
Nurse the baby right before his or her nighttime sleep, and then drink the beer. By the middle of the night, you should experience increased milk production, and the impact of the alcohol on the baby is negligible as your body will have metabolized the alcohol and very little will be in the breast milk supply.
Drink Mother's Milk Tea. There are many versions of this tea on the market in grocery stores. Pick one and follow the directions.
Mix Brewer's yeast into your morning glass of orange juice. Start small, with no more than 1 tsp. Brewer's yeast can not only increase breast milk supply, it has the added benefit of being rich in B vitamins. These vitamins can help regulate your moods as you experience hormonal shifts from birth and breastfeeding. I would definitely recommend sleeping at night with your baby also. In your and your Husband's bed
. That would give you eight more hours or so, of time where your little one can be potentially nursing: You turn over, baby latches on. You go back to sleep.Don't worry about marital relations being affected. The baby dosen't know what is going on between Mom and Dad
.We have 4 and have slept with them all. I hope Erin chimes in on this too. She seems very knowledgeable on nursing. We will pray for you
