Designing for kids room is your call. You oick what you like for your kids. Wall decoration for nursery is not something that you should be overdoing. Just pick few family photographs, some story books, rattles, baby toys in shelves & your kids name stenciled on the wall.
The idea is to decore with some cute baby items that are close to you & some personalization.
