I will tell you exactly why I didn't breast feed my son and chose formula when at the time I may have been considered 'low income' and 'less educated' when I was 20 years old.
-I got WIC assistance which covered about 70% of the cost
-I did not know how to find/was not offered breast feeding support, education, or training. No internet at home, books did not help. It is not something that comes naturally for most mothers and infants.
-No family support
-No husband
-I could not afford a pump that worked to use while I was working
-The manual pump was too hard to use, I couldn't figure out how to get my baby to take to the breast
-Even if the manual pump worked well, I could not stop working every few hours to pump
-Regular benefits such as being able to pump at work are not offered at minimum wage jobs, whether it is the law or not, they will find a reason to get rid of you
-Lower income, less educated people generally work more hours
So, I assume all of the above are typical of low income/education. The whole lifestyle is different and there are different challenges.
Now, at 29 yo w/ my MBA, I am going to try to breast feed. I bought one of the best pumps, I actually get to stay home for a while w/ the baby, I work in an office and can pump at work, I am married and have family support. I know who to call and where to go for assistance if I need help w/ it.
I went from one extreme to the other, so I can compare and contrast
well.
