Taurean, I was in exactly the same situation as you with my DD. She continued to lose weight until she was about 11 days old then started to put it on and was 160g over her birth weight at 2 weeks 2 days. I was freaking out big time when she hadn't started to put weight on after 11 days and was trying to express and feed her that milk as well as offering the breast at least every 3 hrs (whilst being an emotional wreck and crying because I thought I was starving her) My midwife was happy with the 8+ wet nappies per day and loose yellow poos and suggested 3 hrly feeds even if she was asleep. DD went on to have some big weight gains each week after that (300, 450, 380 before it slowed to about 150-200g per week)
Try to to stress as hard as it is, and I hope that you have a good weigh in tomorrow
