Welcome and congrats!
No worries on the intro or the nursery. My oldest didn't have a nursery 'til she was 6 months old. My youngest didn't spend time in hers for about five months. If you've got a car seat, a place for Alex to sleep, some diapers, clothes, and Mylicon by the time he arrives, you'll be fine!
