I don't know how old your baby is but that sounds normal for a regulated milk supply, which happens after the first few weeks usually. You should not have to worry about if breasts are 'empty' or not, you are always making milk anyway (although once supply regulates it may not feel like it.) I agree, it sounds like the block nursing has done its job. Nurse as you and baby please, one side per feeding, both sides, whatever, and pump when convenient.I guess I'm also confused about how to tell if my baby has emptied my breast. They always seem to feel the same...never engorged or anything anymore.
