Going from exclusively pumping to breastfeeding???

Ashley

I tried to breast feed for a few days when she was first born but it was extremely painful because my daughter was born four weeks early and her mouth was too small to get a deep latch. Now she’s three weeks and growing well and i want to try again. I’ve been exclusively pumping and would like to try the breast again. I’ve tried twice today and she just screams. I feel like a failure. Have any moms been successful in this situation? Help?
