I have just returned to work from Mat Leave, and i seem to be having supply issues already! My 4 mo old son is taking down 24 oz of breastmilk in an 8 hour period at daycare and i'm only able to pump about 12 - 16 oz total from three pumping sessions. This seems crazy inadequate. at this rate everything i've stored and am pumpin will be gone in a week. HELP!!
