is it bad to give baby infamil for one bottle feeding then give him similac or gerber formula for…

Babies should really stick to one formula. Is there a reason why you're giving him two different ones?

I'm only giving him infamil but someone have me the other formula and I didn't want to waist it @andrewsmommy

He's doing good with that one @andrewsmommy

you can switch brands as long as it's the same kind. like if you use gentle ease.... you can use any brand of it ... cuz I switched from Similac to Enfamil . hospital said that's fine
