Gassy baby

My daughter is almost one-month and she's really gassy. She passes gas all day and when she burps I can tell that it hurts her a little. I think it's her formula but we're giving her Similac Sensitive to help with the gas and it doesn't seem to be working. We're also giving her Gripe Water and that's not helping either. 😓 Can you parents recommend anything that worked for your baby if they had gas problems?
