That one upset my daughters stomach horribly. Any enfamil product tore her stomach up. We also tried gerber soothe and gerber sensitive. Those messed with her as well.
That's how my daughter was, with the exception of she slept all day and was up all night.... Literally. If she's gassy, you should definitely try a more sensitive formula.
It was a lot of testing different formulas before finding one that worked for her.
