Hi there! I just had B 5 days ago. She is a very aggresive sucker and caused such pain in the hospital (plus I am sure I messed up the latching). Now I have cracks and am trying to heal so I use the nipple shields. Is it ok to continue to use them? Will my nipples ever get to the point wehre they will be rugged enough to endure breastfeeding without the shield? Also, I see it is rec. that baby feeds every 3 hours but mine is a sleeper and if I wake her she will just fall asleep on the breast. I want to make sure my milk comes in properly...any advice? Should I pump???
