seeming this study has come forward.. are they going to do anything about it that anyone has read?

I hope they do.... coz like me, i stopped BFing at 5 weeks and ive tried so many formula's and now mia is on one that suits her, but i would still like to know im not giving her bad stuff.. does that make sense?

question - can someone give me a quick lesson on what pro - biotics are and what do they do??
