Have any other Mama’s noticed a drop in formula intake as solids have increased?

Today and yesterday my daughter only consumed around 18oz (or a lil less) of formula- she has three ‘meals’ a day, some purées some BLW foods, she’s having regular BM’s and wet diapers. I feel silly posting this question but I figured I would start here before calling the pediatrician about low formula intake.. thanks y’all
