There are many benefits for breast feeding over formula. Primarily that of boosting the babies immune system.

There is also growing science showing babies put on formula too early are at greater risk of asthma and allergies.

While i am no expert, I do work with them 8)

I only wish milk banks were used more, I worry these days that many people quickly abandon breastfeeding.

And don't believe me straight up. if anyone is interested to learn more there are a large number of resources on Children Hospital and many other gov't health pages.
