Hello! I am a breastfeeding Mommy 3x. My second had trouble latching on so the lactation recommended the nipple shield, I would use the nipple shield and while latching on my daughter the lactation consultant used a syringe with formula and squeezed the formula into the nipple shield and my daughter latched on after a couple of times and eventually I was able to breastfeed. Hope this helps!
