Absolutely. My daughter was rarely sick as a baby - no allergies, thin as a rail. My little nephew was bottle fed and had colic, ear infections (probably from holding his bottle while lying on his back), and all kinds of troubles. He was a little chunk as a baby too.
And I know people that the opposite was true.
The fact is that it really shouldn't BE AN ISSUE! If women want to breastfeed then GO AHEAD!
if they want to bottle feed then GO AHEAD!
It should be the parents choice and it shouldn't concern anyone else! Why do we, as a society, insist on making a WAR about such a stupid subject??
I breastfed my kids, I can sit here and tell you that I believe it made them smarter, more talented people but how the heck would I ever really know that?? How do I know that they wouldn't be just as healthy and smart if they had been on a bottle??
The real problem in this issue are the people on both sides who want to force the other side to see things THEIR way! The people who want to turn this into a "my way or the highway" kind of issue.
I had one of each. My daughter was, and is, skinny as a rail. My son was such a porker as a baby. Now he's solid as all get out but not fat in the least. My third was inbetween. But none are fat now.
