Hello girls! I have a question for you: how can I resume breastfeeding? I was urgently admitted to the hospital, it seems like I'm going through a period of lactation decline, but milk has disappeared. The baby is 8 months old and he sucks on my breast in small amounts. Can I resume lactation after a week-long break?!!!
