I’ve been using Klaire Labs Ther-Biotic for Infants (http://www.klaire.com/K-TIF_proddetail.htm). (Thanks to MSPIx2 for suggesting this one ). It’s completely allergen free. You can read about their hypoallergenicity policy here (http://www.klaire.com/hypoallergenicity.htm). I started it when my LO was on an antibiotic, but we have continued using it. I can’t say that it’s made a hugely noticeable difference exactly, but I know it’s been good for her. And every little thing helps!
If you’re interested in this product and you’re going to order directly through their website (which I recommend b/c of concerns with refrigerated shipping, etc) PM me and I will give you a hint how to order that someone kindly shared with me b/c they will only let you order through them if you have a doctor’s referral number.
