simply because i think she's adorable:
oh. em. gee.
happiest baby EVA! seriously. but i suppose that isn't too weird because:
when she cries- she gets held
when she pees- she gets her butt wiped
when she poops- it prompts people to say "oh, how CUTE!" (where as if i were to poop in public it would be a cause for alarm...and possibly get me arrested)
when she's hungry- i offer her an endless milk supply
when she wants to laugh- i make odd faces & talk to her in what could possibly be the most annoying voice ever
when she farts- it's adorable & doesn't smell
and the list goes on.
so yeah- i guess her being happy 99% of the time isn't all that odd. go figure.
