Breastfeeding

Izamar • Mother of two beautiful girls, and currently pregnant with my first son🤰🏻💙
I have 37 days until my due date and just wanted to ask if anyone can give me any tips on breastfeeding, especially how to have a great milk supply. With my first i was only able to breast feed her until 3 months then my body stopped producing milk, i really wanted to breast feed until shes 9 months. I want to do better for my second so please does anyone have any tips for me?
