Sabrina / Cindy,
I checked w my hospital nursery and like Cindy said, once expressed, must consume within 4 hrs in room temp. But once fed to baby , must finish within an hour, or throw away after.
Rast, my baby's even smaller than yours. Now 3 weeks old and last weighed, was only 2.75kg. So sad and can't wait to get him to put on more weight.
