Permanent life changes

I've only had sex twice since November. Parenthood has really had a toll on our relationship. I'm just tired allll the time and I never feel sexy. I think things will get better once I get more sleep but it just feels like my baby is nevvveerrrr going to sleep through the night. Feeling frustrated and worried that we don't have sex anymore. Anyone else? Or have tips? I think I need to eat better and exercise again but I just haven't gotten into a strict routine to lose the rest of the baby weight.
