Breastfeeding question

Tatiana • I have a son and a daughter 👫

I’m still BF and pumping, lately I’ve seen a dip in my supply.. usually i will have a lot of bottles for her but lately I’m barley making any. She nurses most days, if I’m not home she will get a bottle.. not too much soilds. I pump regularly too. Anyone else having this problem? Not sure if l should start to supply with formula now..

Any advice? Thanks!
