My LO is a little over 3 months old. I feel like I'm just going to start doing what I can and then giving her formula if she is still hungry. I work 12h shifts and after pumping all day I'll only bring home about 8oz. I can't keep up with her. When we are home she will nurse for over an hour at every feeding and then be hungry again not even an hour later. I just don't feel like she's getting enough from me. She nursed all day today and then I let my husband give her a bottle around supper. She drank 6oz! We started with 4 but she was still hungry after it was gone. I know for sure she doesn't get that much from me when she nurses. Has anyone else had this struggle?
