Knowing which essential oils are safe for kids by age comes down to two numbers: your child's age and the percentage of essential oil in the blend. The Tisserand Institute's recommended dilutions start at 0.1-0.2% for babies under 3 months and reach 1.5-3% for children 6 and older. A few oils, peppermint first among them, wait until age 3.
This guide is educational, not medical advice. Talk to your child's pediatrician before using essential oils on a baby, on a child with asthma or a seizure disorder, or on a child who takes regular medication. The percentages below are the children's half of our essential oil dilution chart, which covers adults. Anything new on a child's skin deserves at least the care you'd give your own, so read how to patch test an essential oil before the first use.
How much should you dilute essential oils for a child at each age?
Dilute to 0.1-0.2% for babies under 3 months, 0.25-0.5% from 3 to 24 months, 1-2% from 2 to 6 years and 1.5-3% from 6 to 12 years. These are the Tisserand Institute's age ranges, based on Essential Oil Safety (2nd edition). Dilution means the share of essential oil in the total blend, by volume.
| Age | Maximum dilution | Drops per 10 ml (2 tsp) of carrier oil | Diffusing | Oils to avoid or limit |
|---|---|---|---|---|
| Under 2: 0-3 months | 0.1-0.2% | Less than 1 drop. Mix 1 drop into 20-30 ml (about 4 tsp to 1 fl oz) instead | Not in the room where the baby sleeps; ask your pediatrician first | Peppermint, wintergreen, sweet birch, camphor, sage |
| Under 2: 3-24 months | 0.25-0.5% | 1 drop (0.33%) | Short sessions only, about 2-3 drops over several hours; no peppermint | As above, plus eucalyptus at 0.5% maximum, never on or near the face |
| 2-6 years | 1-2% | 3-6 drops | Intermittent sessions; peppermint can be diffused from age 3 | Peppermint before 3, then 0.5% maximum; eucalyptus 1% maximum from 3; wintergreen, sweet birch, camphor |
| 6-12 years | 1.5-3% for full-body use | 5-9 drops | Intermittent sessions, as for adults | Wintergreen and sweet birch; undiluted oils; cold-pressed citrus before sun |
At the standard 30 drops per ml, a 10 ml roller holds 300 drops' worth of liquid, so each drop of essential oil adds 0.33%. That's why the newborn range is awkward: 0.2% of 10 ml is 0.6 of a drop. Make a larger batch instead. One drop in 30 ml of carrier gives about 0.11%, and one drop in 20 ml gives about 0.17%.
One detail most charts leave out: under 6, the Institute's percentages apply to any topical use, even a small patch of skin. From 6, they're full-body limits, such as for a massage oil, so a small area can take a slightly stronger blend. Some oils also need a lower dilution than the chart, and some shouldn't be used at all.
That last point matters when you shop. Whether you browse our essential oils for babies and children or another store's kid-friendly range, check each oil against this table and its own product page, because age limits belong to the oil, not to the shelf. Miracle Botanicals publishes GC/MS test reports for every single essential oil on the product page, so you can see what's in the bottle before it goes near a child.
Which essential oils should babies under 2 avoid?
Babies under 2 shouldn't have peppermint oil at all, and wintergreen, sweet birch, camphor and sage oils don't belong in a baby's routine either. Eucalyptus and other oils rich in 1,8-cineole are acceptable only at 0.5% or less, or diffused, and never on or near the face.
The Tisserand Institute explains that menthol in peppermint and 1,8-cineole in eucalyptus can slow breathing and cause neurological problems in some young children. Its updated chart is stricter on peppermint ("best avoided altogether" under 3) than on cineole-rich eucalyptus such as Eucalyptus globulus and E. radiata, which it allows at up to 0.5% under 3. The Institute describes these limits as cautious, if anything a little over-cautious. Keep both away from a child's eyes, nose and mouth.
Wintergreen and sweet birch oils are mostly methyl salicylate, an aspirin-like compound. According to the National Capital Poison Center, swallowing wintergreen oil is roughly like swallowing a large number of adult aspirin tablets.
Camphor and sage are ingestion risks too. The same poison center warns that even a small amount of camphor is dangerous if swallowed, with seizures possible within minutes, and that swallowing more than a very small amount of sage oil has caused seizures in children.
For a premature baby, or one with a breathing or skin condition, no age chart fits. That call belongs to your pediatrician.
Can you diffuse essential oils around a newborn?
Neither the Tisserand Institute's safety guidelines nor the National Capital Poison Center gives a diffusing rule written for newborns, so the cautious default is not to diffuse in the room where a baby under 3 months sleeps. Check with your pediatrician first, especially if the baby was born early or has any breathing problem.
Once a baby is older, diffusing becomes a question of amount. Robert Tisserand, answering parents on the Institute's children's inhalation page, notes that dilution percentages don't apply to diffusion and puts "2-3 drops over several hours" forward as a reasonable guide. Run the diffuser in short bursts rather than all day, and keep the door open so the scent can clear. Our guide to how many drops of essential oil in a diffuser covers drop counts by tank size.
Is peppermint oil safe for kids?
Peppermint oil is best avoided altogether for children under 3. From 3 to 6, the Tisserand Institute allows diffusing it or applying it at up to 0.5%, which works out to no more than 1 drop per 10 ml. From 6, use the normal school-age dilution and keep it away from the face.
Menthol is the reason, and peppermint oil carries a lot of it. On the GC/MS report for the Mentha piperita oil Miracle Botanicals had on sale in October 2026, menthol measured 43.04% of the oil. Batches vary, which is exactly why a published report is useful.
For a 3- to 6-year-old, keep peppermint off the face and nostrils, and off the hands, which end up in mouths and eyes.
Are hydrosols a safer choice for children under 6?
Yes. The Tisserand Institute calls hydrosols a safer option than essential oils for children under 6. A hydrosol is the aromatic water collected during distillation, and it holds a much lower concentration of aromatic compounds than the essential oil from the same plant, so a lavender hydrosol is a gentler first step than a diluted oil.
The Institute's hydrosol guidance doesn't make hydrosols risk-free. Keep them out of eyes, and patch test first on a child with eczema or reactive skin. In the comments on that page, the Institute's team also called a hydrosol a safe diffuser choice near a child under 1.
What changes once a child turns 6?
From age 6, the Tisserand Institute's range rises to 1.5-3%, or 5-9 drops per 10 ml, and that range is for full-body use. Peppermint and eucalyptus no longer carry the special under-6 limits. For most home uses a 1.5% blend is plenty for a school-age child, and there's rarely a reason to start at the top.
Two adult rules arrive with the higher numbers. Children should never get oils straight from the bottle, and our page on applying essential oils neat explains why undiluted use raises the risk of sensitization, an allergic skin reaction that tends to be permanent once it develops. Cold-pressed citrus oils such as lemon or lime can burn skin that goes into the sun, and the list of phototoxic essential oils shows which ones and for how long.
Why do essential oil bottles need to be locked away from children?
Because children who reach a bottle often drink from it, and a small amount can be dangerous. In a study of 4,412 essential oil exposures reported to Australia's NSW Poisons Information Centre from 2014 to 2018, 63% involved children under 15, and as little as 5 ml (1 teaspoon) of some oils can cause life-threatening toxicity in a child.
That Medical Journal of Australia analysis found 80% of exposures were accidental. Another 13% were therapeutic errors, typically an essential oil mistaken for liquid medicine, most often cough syrup. Eucalyptus alone accounted for 46.4% of cases. So store oils away from the medicine cabinet, not beside it.
The Tisserand Institute's safety guidelines note that even 2-year-olds have unscrewed caps and drunk the contents, and that the orifice reducer in the neck helps only a little. Federal rules require child-resistant packaging for liquids with more than 5% methyl salicylate (16 CFR 1700.14), which covers wintergreen and sweet birch. For every other oil, the National Capital Poison Center's advice is to keep bottles locked up, out of sight and reach.
If a child swallows an essential oil, call Poison Control at 1-800-222-1222 right away, even if they seem fine. Coughing or choking after a swallow can mean the oil went into the lungs, which can cause pneumonia. Difficulty breathing or a seizure is a 911 call.
What is the safest way to start using essential oils with your child?
Find your child's age band in the table, mix the lowest dilution in that range, and check every oil against the avoid list before it touches skin or goes in a diffuser. For a baby under 3 months, start with a conversation with your pediatrician rather than a bottle.
