my baby is similar. When he is hungry, he cries loudly and can't wait even for a minute. When he is drinking with bottle, he drinks fast for first 5-10 mins, then play around. While he is being breast-fed, his condition is better. However, he seems to refuse drinking with bottle when I am feeding him. He always turns his head to my breast and seems to ask for breast-feeding when I am holding him. He would not behave like that when he is being fed by the father and granny. That's quite embarassing when we are at some place that breast-feeding is impossible.
