I originally wanted to breastfeed my son, but his jaw was set farther back than normal and I don't have defined nipples so latching on was hard for him. We tried to use a nipple shield, but it wouldn't stay on well at all, and he wound up swallowing more air than milk, so he was miserable and gassy. I switched to formula the first night home because he was so hungry and I just couldn't provide any milk for him. He's 8wks old now and I'd like to at least be able to supplement with expressed breast milk. Is there anything I can do or take to increase my milk supply again.
