Hi D.,
No need to start solids this early. The longer you wait, the better, eating solids too soon can cause allergies later in life. She will get everything she needs from your breastmilk which is best or iron fortified formula as the next choice. Per The Baby Book by Dr.Sears, starter foods at 6 mos are bananas, rice cereal, pears and applesauce. But even at this age you only need a very small amount just to get them started, a fingertipful. I think I remember waiting even longer to start my kids. You need to discover if they still have the tongue-thrust-reflex going on.
Per the book: "Baby's tongue movements and swallowing skills are the first clues to delaying solid foods. In the early months, babies have a tongue-thrust-reflex that causes the tongue to automatically protrude outward when any foreign substance is placed on it. This may be a protective reflex against choking on solids given too early. Between for and six of age many infants do not have good coordination of tongue and swallowing movements for solid foods. An added sign that babies were not designed for early introduction to solid foods is that teeth seldom appear until 6-7 months, further evidence that the young infant is primarily designed to suck, rather than to chew. Not only is the upper end of baby's digestive tract not designed for early solids, neither are baby's insides. A baby's immature intestines are not equipped to handle a variety of foods until around 6 mos, when many digestive enzymes seem to click in. Pediatric allergists discourage early introduction of foods especially if there is a strong family history of food allergies."
Hope this is helpful,
