I wouldn't introduce formula, period. You are planning on giving her the world's best nutrition until she is 6 months old, so why change to something so inferior - and pay for it! At 6 months old you can add in rice cereal and some fruits. If you can do it, keep up with the breastmilk until at least 12 months, at which time you can introduce her to cow's milk and a larger variety of foods and skip the entire, chemical-laden formula all together.
Did you know there are more than 100 nutrients in breastmilk that science still cannot identify? This quote is from the famous pediatrician, Jack Newman:
"Every correction of a deficiency in formulas is advertised as an advance. Fundamentally they are inexact copies based on outdated and incomplete knowledge of what breastmilk is. Formulas contain no antibodies, no living cells, no enzymes, no hormones. They contain much more aluminum, manganese, cadmium and iron than breastmilk. They contain significantly more protein than breastmilk. The proteins and fats are fundamentally different from those in breastmilk. Formulas do not vary from the beginning of the feed to the end of the feed, or from day 1 to day 7 to day 30, or from woman to woman, or from baby to baby... Your breastmilk is made as required to suit your baby. Formulas are made to suit every baby, and thus no baby. Formulas succeed only at making babies grow well, usually, but there is more to breastfeeding than getting the baby to grow quickly."
If you have come this far, do not pay for something so inferior when you are producing liquid gold. Think about this:
The cost of a container of Similac formula that makes 168 oz is $24.00
The cost of buying 168 oz breastmilk from a registered milk bank is $756.00!
Children on formula have higher rates of allergies, obesity, ear infections and illnesses. Here are some more statistics:
Breastfeeding is good for employers. Since artificially fed infants are sick more often and for longer periods than breastfed babies, working mothers who don't breastfeed miss more work. Corporate breastfeeding programs in the US resulted in a 27% decrease in absenteeism and a 36% decrease in health care costs. Working mothers who are supported in the workplace not only miss work less often to care for sick babies, but they tend to be more loyal employees.
The WIC program in the US spends twice a much per mother for formula as it does for food given to nursing mothers. If each WIC baby nursed for six months, the US government could save $450-$800 million in health and welfare costs.
Artificial feeding costs billions of dollars to governments, health care organizations, and families. In many countries, babies who aren't breastfed run the risk of increased death rates from illness, diluted formula, and unsafe water. Choosing not to breastfeed is often a life or death decision in developing countries.
Boobs are Best! :) You are doing great so stick to it and tell the formula CEOs that someone else can pay for their Ferrari!
