Ftm. Noisy boy.

Anyone else have the same experience or is my Baby weird? 6 week old baby boy is the noisiest sleeper. He grunts and wiggles and whines in his sleep. I used to jump up thinking he was awake and needing me, but every time his eyes are closed and he seems relaxed. Now when I hear him, I just wait a while to see if he starts crying or if he gets quiet again. When he actually cries out, I go get him.
