When to Stop Using Red Light for Baby: 1 Minute to Understanding Your Baby's Sleep Needs

Red light is frequently used in nurseries as a gentle night light, allowing parents to check on their babies or give nighttime feeds without overstimulating or disrupting sleep. The appeal of red light stems from its warm hue, which is considered less likely to interfere with melatonin production — the hormone responsible for sleep regulation. But just how long should you keep using a red night light in your baby’s room, and when is the right time to stop?

Typically, red lights are considered safe and beneficial for babies during their first months, especially as they're adjusting to circadian rhythms. However, as your child grows, their sleep needs and environmental sensitivity change. Most experts suggest you can discontinue using a red night light between 12 to 18 months, or whenever your baby starts sleeping comfortably through the night without it. Pay attention to your baby’s reaction: if the light seems to disturb their sleep, causes restlessness, or if they show signs of being able to sleep soundly in complete darkness, it may be time to phase it out.

From a design perspective, as a professional interior designer, I always recommend reassessing your nursery setup as your child reaches new milestones. Transitioning a nursery to a toddler’s room is a fantastic opportunity to update lighting, wall colors, and layout. If you begin exploring these changes, integrating gentle lighting options or considering a smart room planner can support both functionality and style for your growing child’s needs.

Tips 1:

If you decide to stop using the red light, do so gradually—dimming it over several nights or replacing it with a lower wattage bulb can make the transition smoother for your baby.
