It's interesting to see because nutrition for babies vary from country to country... My DD's doctor hasn't allowed DD2 to eat cheese, yogurt etc.
OK. In the UK we give cheese, yogurt and can cook with cow's milk from 6 months (cow's milk not to be used for main drink though) but I understand your reluctance to introduce dairy solids if it is not the norm where you are.
Do you not give solids which include milk, butter, fromage frais, yogurt, cream cheese etc at all then?
I'm not sure what to suggest. At almost 11 months I'm thinking you don't have too long to go before dairy solids are possible (assuming you introduce at 12 months). If she is lactose intolerant (did you cut out dairy from your won diet whilst bf?) maybe look into what other milks are available (such as coconut milk) and perhaps try one of these alternatives for that milk drink at nursery (but not as her only milk until 12 months).
I know it's not ideal. Consistency with the bottle or sippy cup might increase the amount she will take but it might not, and it might take along time, by then she could be approaching 12 months anyway.
I moved to cows milk with DS just under 12 months, again not ideal and not per the guidance, I couldn't get any of his formula anywhere in any of the supermarkets or pharmacies in the town or surrounding areas.
Really at approaching 11 months she should be fine with a morning bf and a night bf so although she likes that additional afternoon bf at the weekend maybe it's time for her (and you) to accept that she is becoming a more grown up eater that takes solids in the day and bf before and after nursery.
http://babywhispererforums.com/index.php?topic=67569.0augustvirgo - your LO is significantly younger than OP's. At 7.5 months milk is still her main food and it is far more important to keep the intake pretty good whether it is formula or breast milk. I would suggest beginning a new thread for your particular difficulty so that more eyes are on it to help you out. xx
