My first child was a C-Section birth she was breech, but was healthy and a happy baby .  I started nursing her 2 hours after birth, but was only able to nurse her till 3 week old. That was until my health interfered with our wonderful nursing experience {while it lasted}.  She went to formula with no problems.  One thing she was not doing was gaining weight like she should of.  She is now almost 5, is a petite little girl, and is doing pretty well. 

My second, the pregnancy was not as easy as the first.  I became gestational diabetic in the last trimester and was controlled by change of eating habits.  I almost had to use insulin shots but started walking 30 minutes a day, every day, so I didn't have to use the shots.  Her birth started early with the doctors help. She was suppose to be a 9 lb. baby but successfully induced early, she weighed in at 8 lbs.  That birthing experience went pretty well without any drugs for the pain.  The nursing experience with my second was even better. she nursed within 30 minutes after birth and nursed for an whole hour.  After leaving the hospital she still nursed great and tried o wean herself at 3 months old, but I let her go part time nursing and the other part formula.  Then she weaned herself fully at 6 months old.. 

My third child my son, his birth was great the pain killers didn't work but shortly after that he arrived at 8 lbs.7 ozs. and also started nursing 30 minutes after birth.  After we came home the nursing experience was the best I have had.  He nursed all the way until he was 11 1/2 months old.  Until I had a thyroid scan done, and the medical personnel didn't asked me if I was nursing.  At that time I had to stop nursing cold turkey because the capsule they used for that testing, Iodine 131, should not be given, or used, in patients that are pregnant or nursing.  The drug goes into the breast tissue and will go through the milk for 3-6 months.  The baby will drink it, and could have thyroid problems now or sometime during their life.  Unfortunately I was not notified until after 5-6 times nursing.

My son doesn't like plain cows milk and has to have it flavored for him to get his calcium.  He also has to get his blood checked for his thyroid levels every month to see if there is a change.  His levels have gone up once and then went back down.  But they have to keep an eye on it to make sure.  Also, since we had to stop nursing because of someone's mistake, his weight gain has slowed down drastically, and his immune system has been down since.

Fortunately I had a lot of resources in my area for breastfeeding moms.  The Air Force base has a Breastfeeding Support Group run by a wonderful woman, and WIC also has counselors to help.  Another good resource for questions about medication while breastfeeding is Dr. Thomas Hale's Breastfeeding Pharmacology Page.  This is a great place to go if you have questions.  Just remember that it is VERY important that everyone involved in your medical care know you are breastfeeding.  In the Military there is not always a choice in which doctor you see (as there is with many insurance companies).  So please, always double check that what medications, test run, or anything done to your body will not affect your baby.
