How can they tell?

In addition to babies now coming with glow in the dark or karate chop action, I've noticed that mine all have these incredible gyroscopic sensors that can tell not only how high off the floor they're being held, but they can intuitively sense where you're taking them. How can they tell that you're no longer standing and doing the soothe-the-baby slow dance, and you're now sitting very tall doing a soothe-the-baby chair slow dance instead?

Last night Frieda woke up around 3, was done eating by 3:30, but I could hear a burp sloshing around in there that just wouldn't come out. Going down the list of 67 different ways to burp an infant one by one (standing or sitting) the clock rolled around to 4am but that burp just wouldn't come out. But what happens when you put a baby down with a burp in there? Sad baby, much spitting up, general distress. I finally gave up, stood to head for bed, and immediately that big, stubborn burp came up. So now I know the secret: just head for bed. I coulda saved myself 25 minutes of concentrated effort. lol

Speaking of whom, she's definitely over her weight slump. This past Tuesday she weighed in at 9 pounds 10 ounces, having gained a pound in just 5 days. Making up for lost time, for sure, and filling out like the gorgeous cherub she is.
