My litle girl, now 8 months, did take a bottle a couple of times but she doesn't seem to like formula and I am fairly lazy when it comes to expressing so when I am at work she makes do with finger food. I am only gone a few hours anyway so not too concerned, esp as I have more than one mummy friend with babies who either won't take a bottle or are too distracted/interested in everything else to nurse well during the day anyway. In answer to your question I think you will find it happens naturally anyway as you start to offer more food, and offer it before instead of after bf. He still needs a lot of bm/formula now as he needs the calories, as I understand it anyway, but by one year old this will change. (edited to say that I meant he will be getting the calories from a lot more sources including cows milk at one year old, didn't mean that he will need less calories...)
