I have a 20 month old dd and she has gone through this on and off, from a different cause, I was giving her apple juice and it was what was causing it. I put her on Garden of Life Primal Defense for Kids, it is a Probiotic and she has had better bm's than she has ever had. I would definately go to your closest health food store, tell one of the staff what she is doing and they will generally have a great step 1 step 2 recommendation for you. It has never failed me, just to be on the safe side make sure you ask them for their best staff member regarding baby's and baby's digestive systems.
