And has it changed since they were born, or did you update as they got older?

Our girls never had much of a theme. LO1 has grey walls with horse bedding, and one horse picture on the wall. The only thing that has changed is the horse stuff, no new wall colors.

LO2 still has the exact same stuff, she's getting new bedding and a big girl bed in the next few months so that will change it a bit. But nothing major for either room...I'm terrible at decorating though!
