No difference. They just change the ingredients slightly so they can advertise it as it’s illegal to advertise stage 1 x
Might sound odd but how are you preparing the formula? That can change the taste x
@Hannah I came here to say this too
No additional nutritional benefits you can stick to stage 1 it’s not necessary to change
They do say babies can stay on stage 1 the whole time
@Hannah i prepare the formula using hotshot and coldshot technique most of the time. Otherwise, mix the formula in 70 degrees water temperature
Don't think there's much difference in Ingredients at all. That's why you get told not to bother with it as there's no benefit and it's often a little more expensive.
