Help! Formula Weight Gain

Christie

Looking for some help or advice. My 10 week old daughter has gained some weight pretty quickly since I stopped producing breast milk and had to head back to work (thanks USA for horrible maternity leave policies) anyway, she was a jaundice baby, born 7 lbs and lost a half pound that first week but gradually gained it back that first month to about 8.5/9 lbs. And after that we had to transition to exclusively formula. She is now 12.5 lbs and just passed the 10 week mark, went from 45% for girls her age to 75% and even our pediatrician said not to be too concerned (yet). But I want to see if any other mamas out here have experienced their baby having rapid weight gain once transitioning to formula. If there’s a certain brain you recommend or anything I can do to remedy this? I don’t want her to be obese, I feel horrible already that I wasn’t able to breastfeed longer. Any help or advice would be appreciated, I just want my baby girl to be happy and healthy but I don’t want her to be over fed. Thanks in advance!
