Does anyone use Target’s Up & Up brand formula?

My daughter usually eats enfamil gentle ease but we once bought her a container of the target brand version of enfamil gentle ease. The container constipated her so we switched her back to enfamil brand. Since enfamil is almost double the price, we decided to try target brand one more time and she seems constipated again. She finished a container of target brand in about a week and we bought a second container to see if maybe she gets used to it. Any experiences? Is her body just getting used to the switch or does it just sound like it’s not the right one for her?
