Please don't ever call DCFS unless you have a legitimate reason believe the child is being harmed. Like half the parents I know with 2+ kids had at least one that was an inconsolable infant. Some babies just cry a lot.

If it's annoying to you you, just imagine being the parents whose responsibility it is to care for an infant who just won't stop crying. You'd have worse sleep deprivation AND the guilt of feeling like a failure!
