Refusing to eat


8mo old is refusing the bottle. She's always been bottle fed so nothing is new. I've tried putting it in the sippy cup, but she refuses it then too. She also is eating less solids. I am constantly offering, but it's a battle. Shes eating about 6oz less than normal. Today is the 4th day.

Everything else is normal. She's happy and energetic. No temp.

Any ideas? Suggestions?
