Supplementing with formula

Donna

Hey mom’s, so I am due back to work in one week from maternity leave and I wanted to start supplementing with formula I have been exclusively breast-feeding this whole time. Today I just mixed half breastmilk and half formula and tried to feed it to my baby and he will not take it he will only take it from the breast does anyone have any suggestions or is anyone else having the same problem thanks!!!! He does take straight breastmilk from the bottle after I pumped it but I wanted to supplement a little with formula to boost my supply...
