Math, yay!

Now that we have to feed Lenny formula for the week (which costs a small fortune), we can track about how much she eats. We fill the bottle with 4 fl oz each time, often she'll finish, sometimes not, sometimes she'll also request a 1 or 2 fl oz snack, so let's assume she's eating 3.5 fl oz each time. She eats about every 3 hours, so that's about 8 times a day, but let's reduce that slightly to 7 for the sake of argument.

1 fl oz = 30 mL
1 mL = 1 g

Each day Lenny then eats 735 g/day.

Last she was at the doctor (about two weeks ago) she weighed 6#14. From what I've read, babies should be expected to put on 1/2 to 1 oz/day early in their lives. Let's split the difference and figure she's gained 3/4 oz/day (although I think she's closer to 1, considering just how much bigger she appears). That would put her at 7#10 (I'm thinking she's closer to 8#, though).

7#10 = 3460 g

735g/3460g = 21%

Lenny is eating then about 1/5 of her body weight every day somehow. That's like me eating 40 lbs of food a day.

Now I know why she sometimes looks like she's struggling so hard when she poops.
