PS- Congrats on the pregnancy. Oh babies! I love newborns, I was just holding my sisters 5 day old yesterday.
I had lots of kefir during pregnancy: about 2-4 cups a day, made with raw goats milk. I never had an ill effects from it, and it was the best middle of the night snack when I would wake up starving.

I consumed tons of kefir during my last pregnancy. My mom and I both make it every day, and I would make one or two smoothies a day with a good cup or so in each. I never had any problems with it.
