Husbands getting no time off

Did anyone else’s husband have no time off after your baby was born? He My husband got a new job 6 months ago so he’s not aloud to have time off yet without risking losing the job. He will be there when our baby is born, and only 3 nights off. We have a 20 month old son too. I’m due any day now and I’m overwhelmed about being alone right away. With our 1st he had 2 months off so it’s definitely different this time. Any advice?
