These kids were over a week early, born yesterday. Still here as the new owner couldn't make it out today afterall. 6.5 and 7.5 pounds. Yesterday about all I could really get them to drink was 4 oz each feeding (I fed 5 times). I added colostrum powder to the pasturized GM for those. Today I gave them more - 6 oz. per feeding, but four times. I've read that people give thier kids "all they can drink" or just 20 oz 4 times a day. Tonight when I fed them their bottle they seemed as if they wanted more. Should I let them have all they want? Can't they get sick from that? Thanks!
