Nursing newborn

Elizabeth

Hey. Just gave birth to baby nunber 2. I had to pump at the hospital so that my milk came in and then supplement with formula. My milk is finally coming in, and I want to nurse baby, not have to exclude pump. I've tried nipple shields before providing a bottle of exressed milk, but he gets desperate ( obviously) because he has to work harder to get the milk. What can I do to help him latch onto the boob? Thanks!
