I was breast fed for 4 months, but because my Mum had 5 children I can remember watching her feeding the youngest 2 (and also gaining the impression that she had fed for far longer than 4 months). The reason I remember is because it was such a special priviledge for me to be in the room with her to sit and watch. I am hoping to breast feed my own child for this very reason - the special feeling that you get from breast feeding. She formula fed after this, so I have seen both methods (btw this was over 25 years ago for the last child!)
