The minimun amount they need from 6-12 months is 20oz a day, this does include the milk in solids but obviously more is better. Are you only giving milk morning, bedtime and dreamfeed now? At 8 months most babies are still on 4 bottles a day, we went to 3 bottles at 8.5 months and then cut out the nightfeed so my DD was having milk at wake up, after lunch, and bedtime. In your case I wouldn't swap to solids first - she needs the milk more. We put breakfast first when DD was 13 months because she was refusing breakfast.
Can you post your EASY - especially the feeding parts for us to see?
