look.. it's FINE. calm down. STOP IT.

You should always follow the recipe on the can unless if the doctor says otherwise. 2X formula is probably never done. But!!! Thickening formula is a thing for babies that won't eat very many ounces.. because it helps get the proper calories into them.

In weeks 11-16 for my baby, the doctor told us to take 5ounces of water, and add 3 scoops of formula.. (instead of 6 ounces and 3 scoops). Because we were working through a feeding aversion and he was only drinking 10-14 ounces a day.

Your baby is fine.. just go back to the correct formula.. she's just been getting extra calories, and her poop has probably been a little thicker.
