Re: Using different formulas?
I would say that they are most definitely not the same. My daughter's poop on Enfamil was very different from her poop on other formulas - she digested them very differently, they smelled differently, the texture was very different.
that being said, I don't see a problem in you using both. If possible, try to use 2 canisters in a row of the same thing (or more) so that it's less stress on their digestive systems, so I'd start collecting the brands from the coupons.
but it's more an issue if you're going back and forth all day long. But over the course of a canister, I imagine you'll be fine.
