Planning on formula feeding from birth

(Sorry if this is the wrong group—I’m not entirely certain where to post this.) I’m planning on formula feeding from birth with my daughter, who is due in just about 3 weeks. I breastfed and pumped for about 12 weeks with my son and had a really hard time decreasing my supply then, and while I know not stimulating my supply will reduce how challenging this is, I do worry about getting mastitis or a painfully clogged duct. Does anyone have advice that worked for them if this was your situation from when your baby was born? TIA!
