Aptamil and mamia formula

Hello, just looking for some advice please. My little girl (6 months) is on aptamil milk, but she’s got enough left in the tub for one more bottle so I need to go get some more. However, the only shop close to me in walking distance is aldi and my partner who drives is at work so I can only go to aldi. Will it be okay to buy aldi milk (mamia) and then tonight go get her aptamil milk as I’ve saw a few people say that mamia milk and aptamil are the same, but just want to make sure this is okay? Thanks for the help☺️
