Is she really my daughter?

It has been six days of trying food, and we have yet to find something she really likes. At first it seemed the avocados weren't a hit, but when followed by banana (marginal, though it seems from her diapers that they had more luck at daycare), sweet potato and carrot, the avocado was the clear winner. Although she'll take a little sweet potato (though certainly not in a restaurant and not when there is a TV on anywhere within 2 blocks), the carrots meet with pursed lips and hostility. Can she really be my daughter??

This morning we tried cereal, which she did eat. I guess it must be the carbs. As you see below, meals start happy enough but quickly turn bad...
