One thing I tell my clients is to really focus in on what you what the nursery to be about. It is easy to overwhelm a nursery (or any room!) with to many ideas! Focus on just a few things and make it really special!
Another important bit of advice is to not limit yourself with to many age specific spaces. You want to think about how your wee little one will grow and how you will (hopefully) still be able to use the space! Think about the big pieces first and make those more translatable for when they grow! Consider spending less money on a crib and getting a dresser that you can double as a changing table and remove later! Then you can bring lots of personality in the smaller items!
Here are a few of my favorite!
