I'm pretty new here so hopefully the experts here will jump in. I've had mine for about two months now and he is 125g. He is probably close to 3 months old though I would say. Length from what I read really doesn't mean much. The weight seems to be more important. 10% is good, but since he seems hungry still I would try 15% of his weight. I've heard 10%-15% and since it's a little one I would lean towards the higher side, especially if it still seems hungry. You could also try feeding every 4 or 5 days. Hope this helps!![]()
