Hey all, my 12 month old daughter is driving me...

Hey all, my 12 month old daughter is driving me nuts with bottles. She was BF till 10 months when I fell pregnant and she went off my milk. She was a real comfort feeder so has now taken up the bottle as her comfort. She has an ok breakfast (before bottle) then can go only an hour before a bottle, then needs another one to settle to sleep two hours later, has a small lunch (as is full of milk from the 2 in the morning) then no afternoon tea (refuses to eat) then demands another bottle mid afternoon and takes 350ml before bed at night. I have tried reducing them but she just cries and clings to me all day and we're both miserable. Should I just take them away completely during the day and be done with it? Anyone done it? Anyone still giving plenty of bottles at this age and not worrying? Thanks heaps, am really torn between having a happy baby and a grumpy hungry one who wont eat!
