Depends on the age. When they are a few months old, they are quite silent. Once, my 3 m.o. sat through my thesis defense without making a sound, ha.

Newborns (without colic) are surprisingly quiet and sleep pretty much all day. Also, the snuggles of babywearing help lengthen naps.

Is may just be me, but I have never been bothered by babies crying. Like it'll make me feel bad for the baby but it doesn't really make me mad.
