no sex life... help

My husband and I have a wonderful relationship, but I'm 3 months pp and we only had sex once and only because we were in a hotel for the night while the grandparents watched baby. We have the baby in our room and bedshare so no action at night. During the day she is constantly needing attention and when she does nap, one of us is usually holding her, my husband has always had a lower than average sex drive, but we would at least have sex once a week, during the pregnancy it was maybe once every other month. Maybe we just got used to not having sex? Idk but I want it back to make our relationship whole again l. Anyone in a similar situation? Any advise??
