Nervous first time dad


I’m due the 21st of Feb and I’m getting nervous and excited! I’m nervous about actually being a mom but my boyfriend is a huge nervous wreck. We’re both first time parents however I worked for years in a childcare center so I have pretty hands on experience and have worked with hundreds of children starting around 6 weeks of age so as far as first time moms go, I’m pretty laid back and relaxed. My boyfriend has never even changed a diaper or been around babies though. What can I say to him to help him be less nervous??
