Ok, so I started out with about a tablespoon of grains.  As per the instructions I was given, I added those grains to 1 cup of milk, and let that mixture set for 2 days, stirring frequently.  When I strained off that batch, it wasn't thick, but  my grains had about doubled in size.  Then, per instructions, I added those grains to 1 cup of milk again, let set for 2 days, stirring frequently.  This time when I strained off the batch, it was rather thick on top before I stirred it.  I again added those grains to 1 cup of milk, stirring frequently.  After 24 hours, it was rather thick on top, and had whey seperated.  I stirred it, strained it, placed that batch in the fridge to mellow.  Now I have about 1/4 C of grains to 2 cups of milk started.  Does this sound about right for just starting with a few grains?  I actually think I may make a smoothie tomorrow with the one cup I have in the fridge.........
