Went to the MW yesterday and had Ruby weighed turns out shes lost weight. She was 7lb 3oz when she was born and then went down to 6lb 10oz. On weighing her as we were leaving the hospital she was back up to 7lb 2oz. Yesterday she weighed 6lb 12lb. We have been feeding her on demand which has been between 4 hrs and 4 and a half and shes taking between 3-4ozs a time. Im BF and FF. I bought Aptimil Easy digest yeasterday as shes been having tummy trouble and have increased her feeds to every 3 hrs. Shes taking 4ozs now. She gets weighed again tommorrow, im really worried.
