Normal?

When you're sleeping in your crib, I carry the monitor everywhere. The weird thing is that lately I've been "hearing" you when you haven't been making any noises. I can stare at the monitor and see that there are no lights indicating noise coming from your room, but I swear I hear your faint cries. From your monitor I can hear the dogs barking, the neighbors mowing and cars driving by loud and clear. But I always hear you whimper quietly, even though you're not making a peep.

Is this normal new parent paranoia or signs of a larger issue?
