Hi, my LO is 3 weeks and I've been BF exclusively. Recently I noticed she's crying for feeding more often and at higher frequency (1.5 to 2.5 hours instead of 3-5 hours). She does not want to sleep after feeding at night and cries when we put her in the cot. My confinement nanny claims she is not full and she is naughty. Do you have any idea why she is like this?
