Making the formula

Jalinar

I used to add 1.5 powder to 3 oz of water. I use enfamil powder formula، it says on the label 1 scoop for 2 oz of water. I add one scoop and estimate the half and then add it it to the water. Sometimes I may use less powder and more water. My question is will this hurt my 9 wks baby? I'm worry of havin too much powder because that causes constipation so I try when estimating the half to make it less other than more
