2nd Baby: Set up Nursery or Wait?

JB

I’m looking for opinions from mommas with 2 or more kiddos! My son will be 2 years 10 months when baby is born at the end of this year. He is still happily sleeping in his crib and has not tried to climb out yet—I don’t want to do the toddler bed transition until I have to 🤣. When baby comes, they will sleep in the master bedroom for at least 6 months. So my question is: should I buy another crib and set up a new nursery for baby knowing I won’t use it for a couple months? Or wait and see if big bro needs to transition between the time baby is born and 6 months of age so I can reuse his crib?
