It is tempting to design the whole nursery around a tiny newborn, but that newborn becomes a toddler astonishingly fast. The loveliest, most economical rooms are the ones designed to grow, with a few adaptable pieces and room to evolve.
A cot that converts to a toddler bed, a chest of drawers with a removable changing top that later becomes ordinary storage, good blackout, and a comfortable chair you will use for years. These are the bones of the room and the things you touch every day, so quality genuinely earns its keep.
Design the room your child grows into, not just the one they arrive in.
A restful palette and a few changeable details, prints, textiles, a mobile, let you refresh the room over the years without starting again. It is gentler on the eye for night feeds, kinder to resale, and far kinder to your budget. Personality is best brought in through the inexpensive, easy-to-change things, because you will want to change them.
