Combo feeding

For those moms that breastfeed and give formula how does that work? I'm starting to get stressed with pumping while at work and not being able to leave my girl for too long in between feedings when I'm home.

Do you breastfeed before work and after work and just give formula during the day while your baby is at daycare? I'm thinking about this but I would still like to breastfeed during the day while I'm home on the weekends. But I'm guessing that's not an option if I dont pump at work..

If anyone has any advice or tips I'm all ears. Thanks!
