It depends on the baby’s acceptance. If you have any friends around who uses S-26 (or other brands) can ask them for abit to try out before buying the whole tin. I’ve tried S-26 but it didn’t work well for my LO, switched to Nan.
I would vote for S26! my children and nieces doing well on it and the formulation has improved. No issues with heatiness or constipation. Can get free sample to try too
My baby is doing fine with S26. Constipation happens when she doesn’t drink enough water
