Are essential oils, lavender products or sleep sprays safe for babies?

Use caution. There is no good evidence they improve a baby’s sleep, and NIH says aromatherapy research needs larger, better studies. Undiluted oils can irritate skin, several oils are poisonous if swallowed, and repeated skin use of lavender and tea tree oils has been linked to breast growth in young boys. Keep oils out of the crib and out of reach, and ask your pediatrician first.

A note on scope: Dr. Sam is a Doctor of Pharmacy and a licensed pharmacist, not a physician. This page explains in general terms how a medicine, supplement or remedy relates to sleep; it does not replace your child’s pediatrician. Check with your child’s pediatrician before giving your child any medicine, supplement or remedy, and follow the product label.

The short answer

A calming scent can be a pleasant part of an adult’s evening. For a baby, the potential harms are concrete and the sleep benefit is unproven.

A scent is usually a hope that something simple will calm bedtime. What calms bedtime is a routine and a way of falling asleep that fit your baby. That is the work Actually Sleeping does, with a plan written by Dr. Sam, a pharmacist.

What the evidence and the regulators say

Weak evidence for sleep. NIH reports that a 2021 review suggested aromatherapy may improve sleep quality, but the researchers said larger and more rigorous studies are needed. These studies were not in babies.
Skin. The AAP notes that some people develop skin irritation when pure, undiluted oils are applied directly to the skin.
Hormone-like effects. A report in the New England Journal of Medicine described three young boys who developed breast growth after repeated use of products containing lavender or tea tree oil. It resolved after the products were stopped, and lab tests showed the oils had weak estrogen-like and anti-androgen effects. The authors concluded the oils probably caused it; NIH notes it is unclear whether the oil was responsible. Either way, it is a reason for caution with daily use on young children.
Poisoning. The CPSC requires child-resistant packaging for wintergreen oil because it contains methyl salicylate, and warns of serious injury or death if young children swallow it. It also requires child-resistant packaging for thin, oily products such as some baby, bath and massage oils, because children under 5 who swallow and inhale them can develop chemical pneumonia.
Chest rubs. The AAP lists mentholated chest rubs for children 2 years and older only.

Diffusers and pillow sprays

There is no good evidence that diffusing oils or spraying bedding improves a baby’s sleep. Sprays put product on the sleep surface, and diffusers put a hot or wet device with a bottle of concentrated oil within reach as babies start to move. Keep the AAP’s safe sleep rule simple: the crib holds only the baby, on the back, on a firm, flat surface, with no soft bedding or other objects.

If you use oils at home

Store every bottle locked and out of sight. Child-resistant is not child-proof.
Do not apply essential oils to a baby’s skin, diluted or not, unless the pediatrician has said to, and keep them away from the face and hands.
Read “sleep” and “calming” product labels for melatonin or other active ingredients.
Call Poison Control at 1-800-222-1222 right away if a child swallows any oil.

What to ask the pediatrician

“Is any scented product safe on my baby’s skin, given eczema or sensitive skin?”
“My child has asthma or wheezes. Should we avoid scents and diffusers at home?”
“What is safe for congestion at my baby’s age?”

No product is the answer to a sleep problem

Babies calm to predictability, not to a smell. The routine, the timing and how a baby falls asleep are what decide the night, and each of them has to fit the baby in front of you. Generic advice on all three is everywhere; getting it right for one baby is the hard part.

Frequently asked

Is it safe to diffuse lavender in my baby’s room?

There is no good evidence it improves a baby’s sleep, and diffusers bring concentrated oil within reach. If you use one, keep it and the oil out of reach and outside the crib area, and ask your pediatrician, especially if your child has asthma or wheezes.

Can lavender baby wash cause problems?

A NEJM report linked repeated use of lavender and tea tree products to breast growth in three young boys, which resolved after stopping. NIH notes the cause is not certain. Unscented products avoid the question.

Which essential oils are most dangerous for children?

The CPSC requires child-resistant packaging for wintergreen oil, which contains methyl salicylate, and warns of serious injury or death if young children swallow it. Treat every oil as a poison and call 1-800-222-1222 if swallowed.

Are baby sleep sprays safe?

Their benefit is unproven, and sprays put product on the sleep surface. Read labels for melatonin or other active ingredients, keep the crib empty and flat, and ask your pediatrician before using them.
