I am returning to work in 7 weeks time and want to continue to BF before and after work if possible. Has anyone tried this without expressing to replace the missed feeds? I am giving DS one bottle formula at 10am and one at 10pm at present. I am expressing at present at these times. Would my milk supply diminish if I didn't express? I would like to BF until he is 6 mths (will be 14 weeks when I return to work).
