I have an 8 month old who has nursed like a champ since day 1. However, I recently had two surgeries (in about a two month period). I pumped both times while recovering but this most recent surgery I had a difficult and long recovery (separated from him for almost a week). Pumping was sporadic and not at all productive. My milk supply is sparse and I'm having to supplement with formula. Can my milk supply be recovered/rebuilt?
