Nursing is a wonderful experience. You share a bond with your children that is physical and emotional and you have a wonderful opportunity to transfer essential nutrients to your children.
It is my opinion that children get immunities and long term health benefits that cannot be matched in any other form. I read every La Leche league book that I could get my hands on in the days of "wine and roses". I learned about the different types of babies and I watched for the symptoms that my child were either a guzzler or a nip napper, etc. It was wonderful to see the correlation between other mothers observations of categories and my own children.
I suggest that you read the Bible out loud during your nursing sessions and Christian literature. Try to keep your mind in a peaceful condition while you are nursing. Talk to your baby in pleasantries and good baby talk. It gives a healthy gentle interaction and I think it encourages peace loving in the children. You can talk baby talk because I think it starts a beautiful new language that is just between you and your children and it starts their ears listening for just your voice. Perhaps God will use your voice to draw them to Himself and replace your voice with His voice, erelong.
Eat a lot of veggies. Greens give the most nutrient value to your milk. I am certain that essential nutrients are stored in the bones and in the bottom of the feet from birth and from the early nursing experiences. I actually decided to detox my body, one day with one of those large magnetic things on the feet. I got a lot of dirt on it after one night sleeping with it. I don't think you are supposed to sleep with it on. Just an hour or two. I got so much dirt on this magnetic strip and my feet and bones haven't been the same since. I blame this on my preservation of the essential nutrients that I had from my mother that I shouldn't have tried to get rid of. Metals are in the bottom of the feet that will take you through your life. They are a preservative. You are giving them to your baby when you nurse. So, choose nursing, even though I decry the losses to my own body from doing this.
