My ND gave it to me. It's a powder. Honestly, we just dump it in his mouth. He doesn't mind it at all, but it is messy. Dusty tried it with a spoon yesterday and that seemed better. I get it all in there and then stuff a boob in his mouth.
She says that it's not a bad idea for c-section babies to take them for their first year as they did not get all the helpful flora they were intended to pick up in the vagina.
As worried as that doc was, I'd at least go check in with your regular doc ASAP. I hope things get better very soon!
