He loves baths, too. He's sleeping most nights through, with the occasional 3am feeding.
He has lost all of his dark hair that he was born with, and has blonde-ish hair now, just like Griffin and Sammy. Speaking of, Oliver loves his big brothers! That is, when they hold still long enough for him to engage them in "conversation."
I'd have to say, though, that Oliver's favorite toy right now is his Mama. And I'm okay with that. :-)
