Though your baby probably could cry himself to sleep, you really don't want him to.
When a child younger than six months old cries, it's always for a legitimate reason. Your little one could be telling you he's hungry, tired, needs to be changed or even just wants to cuddle in the only way he knows how. Babies this young haven't yet learned the cause and effect of their actions, so it's impossible to spoil them. The quicker you respond to your little love's cries, the more comforted he will feel. Prompt attention to his needs will decrease his overall anxiety and cause him to realize that he's important and has worth, which is one of the most valuable lessons he'll ever learn.
