To nest or not to nest


So I'm 34+4 right now and my husband and I have nothing scheduled today, so I told him I think we should put the crib together, get the dresser in the right spot, start washing everything....he is fighting me tooth and nail...saying it's too early. I on the other hand, think if I have the time and energy now, do it now. I'm especially antsy because I'm under close supervision for possible preeclampsia and feel like things could take a turn any day and I wouldn't have anything done. When have you started getting ready? Am I thinking ahead too soon?
