Sleeping babies

The ultrasound picture here is OLD and of J about 20 or 21 weeks gestation.

I confess I like to go and check on my kids at night while they are sleeping, one particular night a little boy reminded me of one of his first pictures I saw of him. Almost always he has a hand by his face and sometimes even both hands like the ultrasound.

It makes me wonder if when he is a teenager or even an adult if he will continue to sleep like this.
