Formula for BF baby


Hello mama’s. 🙋🏼‍♀️ I am EBF & my baby (will be 7 weeks on Friday). Baby has not had formula yet. I will be going away for a weekend and will likely not have enough milk stashed as I had to change my diet recently for baby. Wondering how you introduced formula to baby? Did you do it gradually? One feeding here or there or more? Same amount in the bottle as when you give breast milk? I don’t plan to use it a whole lot. Just to fill in for any feedings I can’t provide for while I’m gone. I will be pumping while I’m gone and when I get back we will go back to EBF. Eventually she will likely transition to formula but that’s to be determined. Thanks for your input!
