Question: are babies fussy at 6 weeks?
Answer: In addition to a short, 2-3 day (or perhaps 1 week) growth spurt at 6 weeks, most babies also experience something that Dr. Weissbluth calls “the peak of fussiness”. By 6 weeks of age, most babies are growing out of their drowsy newborn state, and are starting to perk up and notice the world.
