I have a 5 week old daughter.. I'm mostly pumping (every 2-3 hours), but also feeding her from breast occasionally (2-3 times a day).. I'm worried I'm not producing enough for her.. I've tried supplementing with 2 different kinds of formula (1 time a day/3 oz), but both make her sick (projectile vomit).. Im taking Fenugreek & Blessed Thistle, 3 of each/3 times a day.. How can i be sure she is getting enough? She always acts hungry after feeding, usually drinks all of whats pumped, between 2-4oz..
