Ah! Just when I feel like I've got the hang of this baby thing my glorious DD challenges me again. She is three and a bit months (15 and a half weeks) and lately she has started:

-Screaming at the breast where once she fed beautifully.
-Waking up 20, 30, 60 minutes utterly hysterical after we have put her down for her big sleep at night where once she settled immediately and for 5-6 hours. She is not particularly hungry- if I put her on the boob she only takes a little but if I've had a wine and hubby gives her EBM she guzzles it.
-wakes every three hours at night to feed where she only ever woke up once or twice. Yet she doesn't seem as hungry during the day- feeding every 2.6 to three hours instead of every 2.
-her colic may have come back...maybe?

Is this a usual 3 or 4 month thing? I thought babies did these 360s closer to 6 months? She has had a few big milestones lately- she is already rolling frequently from back to front for example, trying to sit up / forward when lying propped on a pillow, has been laughing and 'talking' heaps.
