First of all, that's great that she is taking solids. And, really, bottles are just not the same as the real thing, so no surprise that she prefers nursing and food to the bottle, right? From 18 months to age 2 my baby was taking solids and nursing just once at night before sleep. During this time I used the phrase "all gone" when he finished his food, often enough I guess, that when I decided to stop nursing when he was two, I used the phrase "all gone", with a smile and a kiss, to let him know we were through. Amazingly he tried to nurse just once more after that and when I said "all gone" he got the message and never asked again! My advise is to keep positive. Know that your love is the most important nourishment of all and baby will feel it as well.
