Fussy Baby Getting More Demanding

My goodness, Darren has becoming more fussy and demanding then ever.
We used to wake up at 1,3 and 6 am to feed him and would spend 20 minutes to put him into sleep. With that he would demand to spend his first 20 minutes in our arms before we could put him back to his crib. That was kinda okay because we had adjusted our schedule and sleeping habbit for that.
But Now, we just realized that his fussiness has just escalated to a higher level. Not only he demands to sleep in our arms full time, he also requires us to swing/make some movement. This baby is getting very hard to deal with... and pushing the limit.
