"Like a Baby"

Whoever coined the phrase "sleeps like a baby" didn't have Jonah!  Wow, he can make the most awful noises.  Mommy and Daddy frequently wake up to monstrous grunts, throat-clearing and other sounds that you would only expect from an old man... and Jonah is still fast asleep!  Even after a week of this, we haven't learned to sleep through - I'm not sure anyone could at that dB level!  Weird that it only happens at night and correlates to the end of his sleep rather than after feeding.  Inclining his mattress doesn't help (nor did Daddy's earplugs).
