... and we can tell because she reacts with gleeful urgency to them:
1. her bottle.
She not only knows the sight of it, but the sound of it as well. We'll try to sneak up on her, shaking it behind our back so as not to have a crying fit (because once the bottle is *there* there's really no good reason it should not be in her mouth *immediately*). But she'll hear the slosh, get wide-eyed and then start looking around frantically.
2. her reflection.
Oh what joy to be held up to a mirror and to realize that a delightful little baby is staring back at you. And there's another daddy--two of them!!! And another mommy too! Wow, this is so freaky cool! It. just. blows. my. mind!!!!!
We've got a mirror on the living room wall that is now covered in dried saliva.
3. other babies/kids.
Why do babies like babies? I don't know, but they do. I've got some anecdotal evidence that they might enjoy finding someone potentially smaller and weaker than them. A friend tells us that her baby (who took away a toy from Sophie) is usually the one to have toys taken away from him. I'm proud to report that on their second encounter, Sophie had apparently wised up and growled at the kid when he came to take he toy again. Babies are just barbarian bullies, apparently.
4. us.
It's so very gratifying to come home to a little face that lights up at the sight of you. Kind of like a dog, only better. Sophie would jump up and lick my face if she could (she does enjoy licking things). In the event she just sort of bounces in place and grunts.
Lately she's been showing signs of realizing that her mother and I are detachable--that we are not, in fact appendages of her own body (though we remain her faithful servants). When passed from the mommy to the daddy or vice versa, she'll take a serious little moment to contemplate what the hell just happened and how it is possible that a second ago one was over THERE, looking over here and now one appears to be HERE, looking back over THERE. Huh.
5. "bleebleebleebluhbluhbluhbleebleebleebleebluhbleebloo"
This would be the sound of a finger moving rapidly up and down over a mouth that's voicing. Is there a technical term for this? Anyway, Sophie loves this. It is absolutely hysterical--my second most funny trick (the first being the bit where HER pacifier is in MY mouth, which is just crazy insane funny).
Now here's the greatest part.
Sophie tries to join in. After "bleeblahbluh-ing" for a bit, if we put a finger up to Sophie's mouth she'll start to go "aaaaahhhhhhhhhhhhhhhhh" and wait for us to move our finger up and down. When successful, it will be HER mouth making the noise. Whereupon she beams in joy.
6. ceiling fans.
I don't know why, but they are fascinating. If they are not moving, she stares at them disappointedly. If they are moving, she stares at them in joy.
