Anyone Supplementing?

Mariah

My little fellow just turned 5 months old and I'm ready to end my breastfeeding journey. I want to preface this by saying I never thought I was gonna be a breastfeeding mama (thought it was just gonna be too tough and stressful). So I'm totally ok with stopping at 5.5-6 months, especially with the 1,000oz I have stored in my freezer. I have a friend who began supplementing half breastmilk with half formula with her milk stash. Is anyone doing it differently? I want it to be gentle on his stomach, so I plan on using the Similac Supplementation formula. Would love any words of wisdom or experiences folks have had in this area?
