formula help

Charlene
Hey moms! Question for my formula feeding mammas. On the container the instructions go 4oz equal 2 scoops and 8 oz equals 4 scoops. Can I do 6 oz and do 3 scoops?? Any moms do this? My baby girl is 6 months, born May 30 and we've been doing 4 oz for so long .... she's been eating a lot more lately but don't think it's necessary and a waste to do an 8 oz.
