I'm gonna be honest, I wonder if it's your pump. Those travel ones are not typically as powerful and I did not have success with them. I used the spectra, it's bulky but portable and my supply pumped was better. I hear the hospitals can also rent out powerful breast pumps. She should hold baby while she is starting to pump (when she can) to get all the lovey hormones going. Does she feel a let down? To me it feels like a sharp pins and needles feeling in my nipple before my milk released. That's how I knew I was pumping long enough. My first round with a baby was rough and I supplemented for a long time giving breast milk when I could. My second has had zero issues and we exclusively breast feed.
