A newly prepared nursery may smell of paint, furniture, flooring or several materials at once. Learn what that odour can and cannot reveal, which sources may contribute, how ventilation changes what parents notice, and practical ways to reduce avoidable exposure before the baby spends extended time in the room.

Why do new cars, freshly painted rooms and fragranced cleaners smell clean? Learn how memory, marketing and material emissions shape that impression, why odour alone cannot measure indoor air quality, and what to check instead of masking the smell.
