We weighed Kyra today before she ate and she weighed 1lb 8 oz, a couple of days ago I weighed her after and she was at 1 lb 12 oz. I don't know if scales are reading wrong or what because Laddy always weighs the same on them. We use a postal scale for them. I don't know whether to be concerned because she lost weight or if this is normal. She is 18 weeks old and I was so excited because I would love her to reach the 3 to 4 lb mark at least. Help anyone?
