I feel like I am always hungry. About thirty minutes after a meal I feel hungry again. Little one (4 months) nurses about every 3 hours during the day but sttn. I've lost 20lbs total since giving birth. I was at 150 before pregnancy gained 15lbs during and now I'm 144. Any ideas for filling nutritious snacks. Is this just part of life now that I'm breastfeeding? I really don't want to lose too much more weight but I want to continue to nurse for at least a year longer.
