worst feeling ever

so, liam tends to wake between 5 and 5:15 since about 6 weeks-now he's 16 weeks...i think...i'm back into thinking months again instead of weeks-rough transition...anyway, so, i wake up at 5:13, look at the video monitor-kid sleeping on stomach-argh-hate that since he can't roll himself back yet-ok, i go back to sleep-i arise at 6:23 a little too rested-first thought OMG SIDS! look at monitor and can see he's definitely alive-he's kicking, the lights on the monitor are going crazy-he's SCREAMING but i can't hear him...somehow the volume was off, and my poor little buddy was stuck on his tummy screaming and i couldn't hear him...i run in to rescue him, pick him up and once he's sees me, he's screaming even more, a new scream-an abandonment scream-as if he's saying "mommy it was so awful, i was stuck on my tummy, i pooped and you didn't come"...so, i nurse him in between his little whines-nurse nurse waaa, nurse waaa, and he finally falls asleep in my arms-i supposed i should be happy i learned the lesson of checking the volume all the time, but i keep thinking of the poor guy all sad screaming for most likely over an hour-worst...feeling...ever
