Karen reported (and I've seen this a couple of times on Lactnet):

> Linda Smiths book "Games and Strategies for Lactation Education" has some
> great facts in it. I like the one:
> "How much formula would a baby need to consume to get the same amount of
> protein found in one ounce of colostrum?
> About 16 ounces"
> This book in invaluable for education.

This puzzled me.  So much, in fact, that I went to Ruth Lawrence to see if I 
could figure it out.  This is what I came up with:


Colostrum on day 1 has 0.96 g/ounce of protein (32 g/L or 1000 ml).  On day 
2, it has 0.51 g/ounce, and on day 3 it has 0.36 g/ounce.  

Similac has 2.07 g of protein/148 ml  which comes out to 0.42 g/ounce.  So on 
day one, as I figure it, colostrum has a bit over twice the amount of protein 
that formula does; 1.3 times as much on day 2, and a bit lower than formula 
on day 3.  

I then wrote to Linda Smith to ask her what I was missing in the equation.  
Here is her response:

That question is INCORRECT, which I discovered after the book was released. I 
wrote that trivia question based on incorrect information. It will not appear 
in the next printing, which is in progress right now.  Feel free to spread 
the word about the error, with my sincere apologies to all. Linda J. Smith, BSE,
