Bottle vs Breast

My little girl breastfeeds for a very short time or even refuses my breast. If my husband bottle feeds her my pumped milk she takes it really well. I know babies can be efficient at the breast and that bottle feeding is less work for them. I’m glad she’s taking the bottle because it helps when I’m working but I’m afraid with the short/refused feedings my milk supply will drop and I won’t be able to feed her enough or pump enough for her to be satisfied.
