I was a breastfed baby for 9 months followed by a healthy homecooked diet but I was also a poorly child with numerous ear infections, chest infections, asthma, convulsions... Just because a child is bottle fed it doesn't cause a child to be, just as breastfeeding won't stop a child becomming ill. Other factors will also play a part!I'm not denying breastfeeding isn't great if you can do it but I dislike the fact those who bottle feed are made to feel so guilty.
