Haakaa

Katie

Can someone explain to me why you would catch your let down while you’re nursing on one side other than the obvious that you don’t want it to go to waste? I am due with my second any day now and bought a haakaa pump but I’m confused, when I had my daughter they told me I needed to nurse on both sides for her to be full, if I collect on one side while I nurse on the other would I not adequately feed her?
