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?

First of all, your confinement nanny is ridiculous. A naughty 3 week old does not exist! Ignore your confinement nanny. As per pp, it sounds like a normal growth spurt. Are you feeding her until she naturally comes off the breast? If she falls asleep, do you try to wake her by tickling under her chin or her feet? This could help to give her a more substantial feed and send her into a deep sleep, so that hopefully moving her to the cot won't wake her.
