For the past day now LO who is 2.5 weeks old has been forcefully spitting up after each feeding. I think I have an over supply, I'm always leaking and it feels like my breasts are always full. I am also using a nipple shield, so I wonder if she is sucking in too much air while she is eating

I'm just so frustrated! I want to keep breast feeding, but I also don't want her uncomfortable. I want to also make sure she's getting enough food. Any suggestions??
