itsme~~ I can understand the pain of feeding every 3 hours, Bethany was still pretty jaundice when we came home and the visiting midwife had us feed her every 3 hours and 75mls (which was a good 15mls more than she had been having) it was 2 days of hell! She hated it we hated it. thankfully she put on weight and the midwife signed her out of the home care program and we were about to go back to demand feeding.
Stick with it but remember noone knows your baby like you.
