This combination of nightlight and white noise maker is so handy that we’re amazed no one thought of it sooner. Controlled via an app from your phone, you can select multiple hues, all of which have been shown to aid in your child’s circadian rhythm, while white noise’s benefits, backed by science, allow for deep, restful sleep all through the night. We especially like its swappable coverlets, which are a fun way to customize its appearance as he or she grows older.
