If your baby has been diagnosed with or you suspect ate part of a houseplant, here is what the evidence says.

The short answer

Key takeaways

Many common houseplants can cause irritation or illness if a baby chews on them. Plants like pothos, philodendron, peace lily, and dieffenbachia contain calcium oxalate crystals that cause immediate burning and swelling in the mouth and throat. While most houseplant exposures cause only mild symptoms, some plants are more dangerous. If your baby has eaten any part of a plant, call Poison Control (1-800-222-1222) with the plant name.
Usually normal when: Your baby briefly mouthed a leaf from a non-toxic plant (such as a spider plant or Boston fern) and shows no symptoms
Call your doctor if: Your baby has significant swelling of the mouth, tongue, or throat, difficulty swallowing, or difficulty breathing after eating any part of a plant — call 911

“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”

This is one of the most common questions parents ask. Searching for answers means you care.

What Parents Should Know

According to Poison Control, AAP, ASPCA guidelines, many common houseplants can cause irritation or illness if a baby chews on them. Plants like pothos, philodendron, peace lily, and dieffenbachia contain calcium oxalate crystals that cause immediate burning and swelling in the mouth and throat. While most houseplant exposures cause only mild symptoms, some plants are more dangerous. If your baby has eaten any part of a plant, call Poison Control (1-800-222-1222) with the plant name. At 6-12 months, crawling babies are drawn to the leaves and soil of floor-level plants. At this age, babies explore by mouthing everything. Even non-toxic plant soil can contain fertilizers, pesticides, or mold that can upset a baby's stomach. Move all plants to high, unreachable locations or to rooms your baby cannot access. It is generally considered normal when your baby briefly mouthed a leaf from a non-toxic plant (such as a spider plant or Boston fern) and shows no symptoms. However, you should contact your pediatrician promptly if your baby has significant swelling of the mouth, tongue, or throat, difficulty swallowing, or difficulty breathing after eating any part of a plant — call 911.

By Age

What to expect by age

6-12 months

Crawling babies are drawn to the leaves and soil of floor-level plants. At this age, babies explore by mouthing everything. Even non-toxic plant soil can contain fertilizers, pesticides, or mold that can upset a baby's stomach. Move all plants to high, unreachable locations or to rooms your baby cannot access.

1-3 years

Toddlers can reach higher surfaces and may pull down hanging plants. They may also dig in plant soil and eat it. This is the peak age for plant ingestion incidents. Common symptoms from calcium oxalate plants include drooling, crying, pawing at the mouth, swelling of the lips or tongue, and refusal to eat. Most symptoms resolve within a few hours.

3-5 years

Older children are less likely to eat plants but may experiment out of curiosity. Teach children not to eat any plant unless a trusted adult says it is food. Continue to identify and remove or relocate any highly toxic plants from your home.

What to Tell Your Pediatrician

Describe when you first noticed ate part of a houseplant and how it has changed over time.
Note your baby's current age and which age-specific patterns you are seeing.
Mention if your baby chewed or swallowed a piece of any houseplant and you are unsure if it is toxic — call Poison Control at 1-800-222-1222 with the plant name.
Mention if your baby has mild mouth irritation, drooling, or fussiness after chewing on a plant.
Bring a list of any questions or observations you want to discuss at the appointment.

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

Adrenoleukodystrophy (ALD) in Babies

X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.

How to Advocate for Your Child's Needs

You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.

Agenesis of the Corpus Callosum (ACC)

Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
