Hi all. I have a 13 week old baby fully breastfed. The first few weeks I had an awful time with it but persevered. Glad I did as I'm enjoying bf now. I've tried to express but I'm having no luck and I loathe expressing plus I can't seem to express much and it just brings back memories of first few weeks which where awful. Anyway I have an all day job interview. I've decided to leave formula for baby. Has anyone else done this just for one day? 8-5. How have you found it?im feeling v guilty!!
