If your 9 month old is on a sensitive formula- earths best. and her stools are whole and not super soft and very little maybe thumb sized once every 2 days SOMETIMES but never more than a day in a row would you switch their formula? When she was breast fed she had great stool I think- and now it’s a hit or miss of watery stool. Sometimes it’s both. Her pediatrician told Me to offer P foods and water which I have but not much is changed. This is a more of what you would Do?
