More ounces when mixed formula??

Eileen

Hello! I am a formula feeding momma. I noticed when accurately mixing the water and formula (similac probsensitive) I end up getting more ounces when the formula is added. I am adding the correct amount each time. Is there something else I should be doing?

I just got the dr browns formula mixer to use also and I made 24 oz with them 12 scoops formula and it ended up being close to 28 ounces then!

Thanks for your help 😊
