Hi There, When my daughter turned 6 months old (the recommended time to introduce solids) I found myself in a simular predicament.  My daughter is an incredibly slow bottle feeder but insisted on having all of her 5 200ml bottles of formula per day even if it meant staying up until the wee hours of the morning until she got the last drop in.  I found that giving her a feed of solids could put us back on this bottle schedual by 2 hours which was a sleep depriving torment for both of us.  I would try feeding her thinking it would replace a bottle, but this was not to be.  Finally at 8.5 months we dropped a bottle and for the first time we have a 9.30pm bed time (BLISS).  It all began with my Mum having her special diet smoothy for breakfast.  She gave my bub a bit and bub LOVED it, so I made her one of her own out of formula, farax and fruit (usually banana and or strawberries) whizzed it up with the blend stick and she downed 150 mls with gusto, this is now her fave breakfast, I have however this past week been giving her some wheat bix with whole milk and her fave custard (one tea spon as she LOVES it) and she will happily eat about half of this concoction (made from half a wheat bix before she downs her smoothy, I have also been offering her some english muffin fingers to suck to death which she is also now happy to give a go with.  The key (what I learned with my child anyway) is to have them take in enough of something to lagitamately drop a bottle.  she also has morning tea, lunch, afternoon tea and dinner, but they consist of less food than the big breakfast.

I tried all the things that were recommended at first and nothing worked.  Also it is helpful that you eat something simular at the same time as you feed them, as they do try to emulate you.  My daughter loves nothing better than being fed from my plate and will try anything with no problem, if I do some just for her of the same stuff she doesn't even want to try it.

I hope this can help you a bit, I know it is a difficult mile stone to get through.  Also forget the text books, I'm sure you gave birth to a little person and not a book.  I have begun to really resent the inclination that al babies of a certain age should all be doing the same thing, and if they don't you have to consult a specialist.  I am greatful to all the advice and help I have received, but my daughter has quirks, likes and dislikes, and is great at somethings and not so great at others, just like me, just like every other taller person than her. 

Just don't stress your self out by thinking your bub should be doing something sooner or what ever in the food stakes, it'll happen.

When I first stared weaning Amy she had baby rice made up with formula milk and i used formula milk when cooking food for her. I will still give as much milk as you did before weaning and start with only one weaning feed a day eventually as food increases the baby may take less formula. Amy is now 2 and eats whatever we do but she also has about a pint of whole cows milk a day too. Look at your local health authority site (health visitors etc) they may have advice on weaning.

If you're introducing solids between 4-6 months, I think the recommended liquid intake should still be 6-8oz. liquid and about 1-2 tsp.of solids (cereal, pureed food) before the bottle or breast, every 4 hours.  I've always introduced new foods in the morning or lunch time and for 3-4 days to avoid any allergic reactions or tummy aches. 

I found  a couple of websites that can answer more questions about the type of solid foods and how to introduce them: http://www.babycenter.com/refcap/baby/babyfeeding/113.html

What a fun and exciting time! Good luck.
