My son usually sleeps in 4-5 hour blocks at night, usually he'd wake up, take a bottle, rock for 5-10 minutes, maybe go to sleep. If no sleep, repeat rocking, singing. Last night he fell asleep on his own after the bottle, today he fell asleep on his own for 2/3 naps so far.
It seems like the day he hit 6 months he started wanting to be grown up! He's almost crawling now too. I'm still impressed with how new skills appear so suddenly and are mastered.
