We started on S26 as the supplement to EBM and the short BF month. Once we weren't BF young Riley would go a few days often up to four, without a pebble. He had some refulx on S26 Gold---> We had done the brown sugar thing (and stood up for ourselves often with MCHNs but who cares!) as a back up when he did become uncomfortable and unsettled for no reason and he went like a steam train. We switched to Karicare Gold Plus and have never looked back. He has had much more settled bowel habits.

The biggest guide I used was how bub seemed. If he was happy then fine don't worry. If he is clearly grizzly without a good indentifiable reason then consider intervening.

If you are moving beyond standard and plus formulas I would keep in touch with your doc. Many of them recommend this on the tin, but you change when your feel it's right. Give bub a week or two to get used to the change then reassess how she is.
