The lilac color is ideal for decor of the little girls because it is delicate and feminine. It is also a good option to get out a bit of the classic pink to encourage a different and interesting tonality.
You can combine with white to achieve more delicacy in the style of the bedroom.
I found the night table in the shape of a bird house a good idea. Surely you will come out of the classic to apply a fun and original design to this atmosphere of the house.
You can use the design to have it done to you so you can choose colors and size. Use the help of a carpenter friend or if you are handyman choose to create yourself.
