Making time to have sex

Okay so me and my SO are having a hard time finding the time to get it on lol he usually gets home around 6 so by that time it’s time to eat dinner, give the baby a bath and start winding down for the night. The problem is the baby won’t go to sleep without someone holding him. And after a long work day my SO is usually exhausted so by the time the baby’s sleeping he’s sleeping!!!! We literally have sex like once a month and I can’t take it anymore lol any advice?!
