Please Help! Feeding issue

Rachel

So our baby is a week old, born c section, feeding formula. She was a big girl 9lbs 9oz... when we left hospital Sunday she weighed 9.4 which they had no issues with... go to the pediatrician Tuesday she is still 9.4... recheck weight again today she is still 9.4... had to feed a bottle in office and weigh again to show she held it.. then got sent for baby to do blood work- everything came back good. Going again for weight check tomorrow AM. PLEASE HELP! Very upset mama over here- been crying off and on all day and just will take any advice or good thoughts our way for her weigh in tomorrow.
