What do I need to buy?

Hi parents! I intend to breastfeed my baby after birth. I didn't get the chance to do so with my other kids as my milk supply was really low even with Fenugreek. I also intend to bottle feed my bm just in case my nipples hurts/cracks. What do I really need to buy? The essential things for breastfeeding. I know breastpump is needed. What else? Also, what should I do to increase my bm? TIA for your advice & help ☺️
