Well I have few questions first....has she always been like this or has it been more recently? Does she make eye contact with you? Is she communicative? Is she smiley? Does she ever reach for you? Do you tend to meet all her needs before she can ask for anything? If she's strong willed then you have to watch out for becoming her servant-she needs to need you and be thankful, not control you. It could be a controlling thing or it could be something deeper (like food allergies) which is why I'm asking so many questions...maybe someone else would have some other thoughts/advice.
