Thats not strictly true Emma! Babies are babies everywhere
"The American Academy of Pediatrics recommends starting solid foods at 4 ? 6 months. What many mothers don?t realize is that the four month recommendation applies more to formula fed infants, and the six month recommendation applies more to breastfed infants. This is because formula is not as complete a food as breastmilk, and formula fed babies are more likely to become anaemic than babies who are breastfed, so they need iron-enriched food earlier.
The most important thing to remember is that breastmilk is a nutrient dense food and should be the primary source of your baby?s nutrition throughout the entire first year of life while his brain is growing so rapidly. It is the ideal source of nourishment, and it?s composition changes to meet your growing babies needs. For example, the levels of antibodies in your milk increase as your baby starts solids and takes in less volume of milk, and the fat levels in the milk decrease as your baby slows down on his weight gain in the second six months of life.
According to Ted Greiner, Ph.D and noted breastfeeding researcher, any foods other than breastmilk or formula given during the first 6 months have a displacement rather than additive effect because they displace the fat and calories the baby needs from milk....
Besides the fact that your baby doesn?t nutritionally need any other foods until at least the middle of his first year of life, there are some other good reasons for not rushing into introducing solid foods into his diet. Intestinal and developmental readiness vary widely from baby to baby. A baby?s immature digestive tract isn?t prepared to handle a wide variety of foods until at least six months, when many digestive enzymes seem to click in. This is especially important if you have a family history of allergies. The protective protein IgA, which coats the baby?s intestines and prevents the passage of harmful allergen, doesn?t reach peak production until around seven months of age."
In view of this Lea2003, as your DD is b/f and already has enough to be dealing with (reflux) I would be inclined to agree with bobthebaby. But I would do some more research and perhaps talk to a doctor you trust before making your decision. How old is she, is she having any treatment for her reflux?
