Did he really just put himself to sleep??

Did Jacob really just put himself to sleep all by himself for the first time ever!?!?! Usually it takes either some rocking or some time nursing before he will fall asleep unless of course he is in the car. I nursed him and he wasn't wanting to sleep. So I put him in his crib, turned the music part of the mobile on, listended to him talk to himself for a few minutes, checked on him when he got quiet and what did i find?? A sleeping baby nestled against his bumper pad with eyes closed!! Maybe I won't dread bed time once he is weaned in 3 months anymore.
