Hi Micaela,

I have references on this, but finding them in a hurry is the problem, as I 
filed them on different USBs according to what where I was speaking or what 
i was writing when using the information. (I need a better system!) With 
immone factors, as i understand it, basically as the volume of milk goes 
down, the concentration goes up. The role of fats and essential fatty acids 
in the second year is covered in the following paper - I have no time this 
morning to find a more recent one.

- Prentice AM, Paul AA. Fat and energy needs of children in developing 
countries. American Journal of Clinical Nutrition 2000; 72 (5 Suppl): 
12535-12655.

There's a short section on the composition of human milk during slow weaning 
in the 7th edition of lawrence & Lawrence (pp. 330-331) and a search of 
components one by one will find more detail. I'm sure others on Lactnet will 
provide more references.
