Her pink wooden high chair. I knew that I wanted to find a unique high chair for her to sit in while eating her smash cake. I happened to stumble across this one at a consignment shop and painted it pink to match the decor. I love how it turned out.
Have fun and definitely start planning quite a bit in advance. It is possible to go all out with a themed party and not spend a ton of money. DIYing as much as possible definitely helped to keep my budget under control.
