EBF baby won't take a bottle ... cereal time?

CC • 🌸 Mommy to Sydney 🙏🏻 TTC baby #2
My DD won't drink from a bottle and I've just returned to work. I've tried so many bottles and even dream feeding, nothing works. I really need to ensure my baby is eating when I'm gone so I don't have to continue to leave the office every 3-4 hours to feed her. Has anyone had this experience and introduced spoon feeding either rice cereal or oatmeal mixed with breastmilk? I'm considering it, but of course waiting until my little ones 4 month checkup to consult with the doctor. She's 3 months old as of today ... I'm desperate. HELP!
