Oh honey, my kids are 6, 4, and 2 and most days I'm STILL not in the mood (lol!) You JUST had a baby. Give yourself some time to heal. It took you 9 months to grow a baby, expect it to take 9 months to get back to your prebaby self. That is in shape, size, and sex drive.
Also keep in mind, that right now you are focusing a lot of your attention to your newborn. This is normal normal normal for women to feel after having a baby.
It sounds like you are doing fine, ask him to initiate it if you enjoy it once it gets started. Tell him you are tired and expectedly distracted. Tell him when you are having a good day, and plan on making time for each other when you are not so tired.
Good luck,
J.
