Hmm. Libido? What's that? Yeah, feelin' your pain here. My son just turned a year old almost two weeks ago, and I haven't had sex with my partner since BEFORE I gave birth. We don't really talk about it, but maybe we should. Have you talked to your husband about this issue? He may actually have some ideas of his own. For me personally, I'm so caught up in working full-time (I'm actually building a new career), taking care of the baby and the house and our financial responsibilities and feeding us and whatever else I have to do during the day that I rarely even think about sex until it's too late (literally, late at night when sleep is the primary goal). Oh, and did I mention that we co-sleep with my son? If you haven't done so already, I think the first step is talking to your partner to find out how much this is actually affecting him, and if it isn't, maybe you can give yourself a break and allow your body to work this out naturally. I think it's quite common for moms to not have a huge sex drive after giving birth and caring for someone 24/7/365.
I hope that you can find a simple solution to your problem, and also forgive yourself for being a different person after bringing life into the world.
I wish you the best of luck, and also, if you do find out anything, let me know.
Take care,
M.
