Question: Any of you Mama's who either exclusively breastfeed or pump have to start supplementing with formula? Or switch over to formula? What's your experiences?

I'm struggling with my supply and I'm just barely able to pump enough for his bottles for daycare. and that's with getting up a couple times in the middle of the night as well as throughout my work day. I'm not sure if I'll be able to keep this up much longer since he's started taking more oz's recently. Just curious if anyone supplements or has switched. How did it go, notice any changes?

Thanks!
