Ftm 😬😬

Is it ok to mix formulas?

My baby girl is 4 weeks 5 days, they started her at the hospital with the similac pro-sensitive (ready to feed formula) and I was doing that till about a week ago, a friend gift me this power milk, but they are all different, and also gift me some coupons for Enfamil, which I really want to use because I looked it up and it’s cheaper.

But I was just wondering if it was ok to mix the power formulas. I asked my ped and she said that it was fine, to just do a bottle of one and then a bottle of the other.

But again I’m a ftm and just wanted some of y’all’s opinions.

I don’t want to just keep the power milk and it go to waste 😕🤷🏻‍♀️

I was given her a bottle of the ready to feed formula that I already had and a bottle of the enfamil sensitive power milk and I didn’t see much change in her poop, just a tiny bit more yellow and a tiny bit for solid, but no diarrhea or constipation, and I’ve been doing that for about 4 days now.
