So my daughter is 11 weeks old. I breast feed and supplement with formula. Ever since she left the hospital, she’s been on similac pro advance. Lately she’s been drinking more formula than my breast milk bcz of my low supply, however, formula is expensive. I found this tub at Sams for waaaay cheaper. I know it says “compares to the nutrition of similac pro-advance” but idk if it’s a good idea to switch to that sams brand bcz it’s cheaper. Ladies what do you think ? The last thing I want is to mess with my daughter’s stomach....
