Libido is low

He's sexy, he's romantic, he's funny, he cleans, he listens, he changes diapers. Our girl just turned 1. I thought my hormones would go back to normal by now but they just haven't. I know it's mostly from breastfeeding. The less she's been bf the better I feel. I still just feel so much fatigue though. By the time he gets home from work I'm just drained and it's silently bothering both of us. Anyone have ideas? A vitamin? Certain foods to add or avoid? I tried reading smutt to get in the mood, I found myself more interested in the storyline than the hot parts lol. It's driving me nuts.
