Tristan can't decide if he wants to be a light sleeper or a heavy sleeper. Most of the time he is a light sleeper and he wakes up with every little noise or nudge. But every once in awhile he is impossible to wake up. Like when we are trying to wake him up so that he will sleep at night. Anyway in this picture he used to be on his side next to Phil but he jerked in his sleep and flopped right onto his tummy. Did this wake him up? No. But heaven forbid we try and lay him down if he falls asleep in our arms.
