With a bath-time puppy, scale decides whether the nursery wakes up. Go small and it slips into a corner; go a touch bigger and it becomes the piece a small child looks at first. The soft mint, cream and buttery yellow keep the wall calm rather than busy, so the room still feels restful at nap time. Hang it above a changing table, a low dresser or a reading nook chair at child eye-level once they’re standing. Pair with pale wood, white-painted furniture and a soft cream or oat rug. Skip dark heavy frames and bold primary-coloured decor nearby they’ll pull all the softness out of it.
