During the night my 7-week-old will fuss in his sleep (grunt, flail, etc...). This fussing rarely proceeds to crying but he usually will not settle on his own. When I pick him up he will usually settle down and most of the time he is wet.
I typically treat this fussing the same as all out crying and respond to him immediately but it has been suggested to me that I may want to let him "fuss it out" for a while so learns to settle himself down (or at least until he starts crying).
Should I treat fussing the same as crying?
