I don't think my son fully grasps the understanding of mommy is sleeping. I'll be asleep for a while and then the next thing I know *wiggle.. roll.. punch.. kick.. wave.. take personal swimming classes...* he is moving non stop and it ALWAYS wakes me up! then I can never get comfortable so falling back asleep takes a while. but! whenever my little man is sleeping, its on his own time and my life has to continue on...with or without sleep
