Mrs s tell the rude nurses to f off! They had me in tears too by the end of my stay with my boys! Your volume sounds fine and the colostrum will not really increase. Did you breast feed last time? If so your milk should come in earlier this time. Are they feeding the boys the colstrum yet or still by tubes? If you have given them a few syringes already than you are already winning the race!!! Do not let them make you feel bad you can do it! In a couple of days you are going to have so much milk it won't be funny! Exclusively bf babies have only the colstrum for the first few days and are fine! I found the nurses tend to get panicked over prem twins when mum chooses to give bf a go. And you know what if all else fails they will have something to feed them ... Formula! So don't let them get you down you are doing great!
