2nd baby comes early?

Jennifer
So everyone keeps telling me I'm going to have my boy early because he's my second. I had my first 15 years ago at 38 weeks. Doe anyone know this to be true? Second are always early? 
I'm due 12/18 and my stepdaughter's bday is 12/9, I'm hoping he comes late so it doesn't make her bday less special. 🙏🏼
Thanks!
