Switching to formula from breastfeeding

Erica

So I’ve started giving my 2 wk old more formula then breastmilk to try and slow down my milk supply from coming in. Do any of you ladies have any advice on how to dry up and/or slow down your milk supply from coming in?? My breasts have been so engorged all day, I know it’s a supply and demand issue that’s why I’ve been only breastfeeding once a day but any advice would help
