Okay, here's what we learned with our boy when he was having digestive problems. IF you switch a formula it takes a good week or 2 to notice changes. And switching often isn't good for them and makes problems worse. If you are going to switch it needs to be gradual. And if they have severe problems the best thing is to put them on Nutramigen for a month, let their system settle then introduce the next formula. When doing this we mixed 4 cups of water at a time and scoop by scoop adjusted the mix....so 15 scoops nutramigen and 1 scoop new formula. Then day by day adjust one scoop at a time. Their systems are soooo sensitive and sudden changes makes problems worse, for you and them. It's a learning process!!! Good luck.
