DD is 7 weeks. Has been such a placid baby, feeding every 2-3 hours, awake and happy for an hour then sometimes going back in the breast to fall asleep, and sleeping until the next feed. Life was easy (with a 3 year old added in!). Now, for 4 days (so I presume this now means forevermore) she is happy for precisely 5-10 minutes after a feed then becomes such a cranky pants!!! On and off the breast until finally falling asleep for half an hour max (including in the sling). I'm seriously going to lose it. I can't cope with DD1 and a baby who is only happy on the boob! Also can't really hand her off to DH for a break because she screams! What has happened???
