I am having the same issue too... LO keeps waking up during an extended period... LO is coming to 7weeks too. Maybe it is some behaviour change during this stage. What to do? Just tolerate lor. I don't think it is colic though, cos if colic they will cry no matter where u put them or what u do.
Jiayou... Think it is gd at least ur hubby is helping u in this difficult stage, though he lost his patience.
Seems like 7-8 weeks is the start of cranky bb. Tot I'm he only one but some of you are also experiencing the same thing too. Told my hubby we just have to be more patient and tolerate. Not an easy fast especially if we are not getting enough sleep.
