The Sleep Guide:

The Ideal Sleep Environment for Babies and Kids

The space where your baby and young children sleep, can have a great impact on their sleep quality.

While it used to be advice that babies should sleep in noise, bright rooms to make them be flexible to sleep anywhere and know that it was day time, science sleep data tells us different. Creating a  sleep friendly environment is one of the first steps to create healthy sleep habits and support better sleep.

A sleep environment that is very dark, quiet, cool, and comfortable can improve your children’s sleep (and yours).

Sleep Friendly Environment
Select a topic.

  • Keep a quiet bedroom to allow restful sleep.
  • Many sleep professionals will recommend using white noise to block sounds from waking a child unnecessarily.
  • The current recommendation is for noise machines not to exceed 50dB, or about the noise level of a bathroom shower.
  • White noise machines should not be place next to your child's year, or in the crib.

  •  Artificial light at night has a negative effect on sleep.

  • Light increases alertness and delays when the body begins to produce the hormone melatonin that signals when to sleep.

  • Keep your children's bedroom dark at night.

  • If they need a night light on to feel safe, make sure you choose lights in the red/orange spectrum that are less disrupting to melatonin production.

  • Anything interesting in your child’s sleep environment can cause them to fight sleep.

  • Keep electronics outside the bedroom where they sleep.
  • Not only electronics represent a distraction for sleep but also the blue lights from screens tell the body is daytime instead of night time.
  • Electronic devices in the bedroom are associated with less sleep at night and poorer quality sleep.

  • Check out our Safe Sleep Guide to follow the AAP recommendation on safe sleep for babies from 0 - 12 months.

  • For older children, it is also important to make sure the sleep environment is child safe proof with electrical outlet covered and furniture attached to the walls.
  • If your toddler is already in a toddler's bed or climbing out of the crib, make sure they don't have access to other rooms in the house that might be dangerous for them to explore during the night if they wake up.
