@misssnow, anytime! I know the pain! And I combine because we always did from the start because my daughter was low birth weight. I think it's great I enjoy breastfeeding but like the relief of a bottle so others can help.
My doctor say some breastfeed babies don't poop but once a week but I combination feed and my baby poops every other day if not every day. I know it's difficult for a baby though try giving her a warm bath to help!
