Asher recently started flipping over onto his tummy to sleep. I was worried about this at first--I keep hearing that babies should sleep on their backs to reduce the threat of SIDS, plus the second night of tummy-flipping, we were staying in a hotel with a big marshmallow of a foam bed and I was worried his face would get swallowed up--but my sister assured me that once babies start turning over on their own to sleep, they're ready for it.
I love watching Asher sleep (I love watching him awake, too. I just love watching him, in general.) Since he was born, his arm has been a barometer of the depth of his sleep. He will often fall asleep with his arm sticking straight up, perpendicular to the bed, as if he is hailing a cab. As he descends into slumber, the arm lowers to the mattress, sometimes with such incremental, controlled slowness, it looks like he is doing yoga, or maybe even a Noh dance. It is amazing to me that a baby's arm can have such controlled and graceful movement, especially while it's fighting gravity. Sometimes, though, his arm will drop to the bed with a sudden thud, and the thwack of it will wake him back up.
Now that he is sleeping on his tummy more, the arm-as-barometer isn't happening as often. I'm going to miss it when it's no longer part of his sleep repertoire. It's funny how I'm already nostalgic about Asher's babyhood; I was at a store today and sighed when I saw the three month clothes. It all happens so quickly; I can't believe he'll be six months old soon (and he's already wearing 9 month outfits). My sweet slumbering boy.
