Our little girl is 3 days old and breastfeeding taking so much out of me it's making me ill. She only goes an hour and a half between feeds and latches for an hour at a time. Because of this I'm barely getting any sleep which is making me ill. I tried expressing today but only producing 1oz so half an ounce per boob. Which would take me all day expressing to produce enough to store and use for her. Thinking of switching to formula but I feel so bad and guilty for even thinking of switching.
