I pray you will have peaceful and wonderful pregnancy this time. You are right about the thyroid gland being so important. About nine months after my first son was born and breastfeeding was such a fiasco, I went to a doctor and he imediatly checked my thyroid and found I was very hypothyroid. A little pill I take every morning is all it takes for me to stay feeling good. When the need to change my dosage is apparnt to my husband or mother, I go to doctor to check it out, and get a new doseage level. My second pregancy was carefully moniterd for the thyroid and now that my baby is here, I feel great, happy, peaceful, and am bottlefeeding him.
