which formula?

Sarah • Mommy to my 👸 . Baby girl #2 due Oct 1st.
Can you ladies suggest a formula my baby. She has gas issues and gets fussy. I breast feed her and only give her a formula when we are out of the house. I have noticed that she only responds well to the ready to feed 2 oz bottles and does not drink the powdered formula. So far I have tried similac advance and enfamil gentle ease. Received both as samples. TIA
