Breastfeeding and pumping milk

Any mummies have difficulty breastfeeding baby or prefer to pump and feed baby through bottle? I breastfed a few days but it is hard to settle into a position where baby latches well, until baby cries loudly. For me, my nipple cracked and also each time it is quite frustrating. It is ok to give up breastfeeding but still provides bm for baby by pumping right?
