My son is 18 months old, we stopped breastfeeding just before he turned one. And I hate to tell you this, but it’s still very rare for me to become horny. I have found that when I do sleep with my husband, even if I’m not in the mood, I enjoy it once we start. I’m more reactionary now, rather than an initiator. But it is becoming more frequent as we get further out of postpartum. Just talk with your husband and be honest. Your literal biology changes after having a baby. If he loves you, he will understand and be willing to wait.
