Safe? Changing formulas.....help please

Is it ok to change formula brands for baby? We started on one brand, but the store was sold out so my husband brought home a different brand. Is is safe for the baby's tummy to just change formula brands?

His tummy might take some time to get use to the new one but I think it will be ok. Just don't be changing it too much.

it should be! i have had to change my sons formula like 3 times already cause he has bad acid reflux :/ as long as its not too much cause it could upset his belly!

It can cause an upset tummy. Just try not to change it to much.
