PFAS (Forever Chemicals) in Baby Products: What Parents Should Know
The short answer
PFAS (per- and polyfluoroalkyl substances), often called "forever chemicals" because they persist in the environment and the human body for years, have been detected in a range of baby products including waterproof bibs, stain-resistant clothing, crib mattress covers, nursing pillows, and food packaging. A 2021 study in Environmental Science & Technology Letters found PFAS indicators in 65% of stain- and water-resistant textile products tested. The EPA classifies certain PFAS compounds (PFOA and PFOS) as having "no safe level" in drinking water. While the long-term effects of PFAS exposure in infants are still being researched, studies have linked PFAS exposure to immune system effects, thyroid disruption, and developmental concerns. To reduce exposure: choose untreated cotton or organic fabrics, avoid marketing terms like "waterproof," "stain-resistant," or "water-repellent" on soft goods, wash new baby clothes before first use, and use PFAS-free alternatives when available.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-6 months
Newborns have the highest vulnerability to chemical exposures due to their small body size, developing organ systems, and frequent hand-to-mouth behavior. Common PFAS exposure sources at this age include waterproof mattress protectors, nursing pillows with stain-resistant covers, and waterproof changing pad covers. Choose untreated cotton or wool mattress protectors. Wash all new clothing, bedding, and fabric items before use. Breastfeeding mothers should know that PFAS can be present in breast milk — however, the AAP still recommends breastfeeding as the benefits far outweigh this exposure risk.
6-12 months
As babies begin eating solids and become more mobile, exposure sources expand to include waterproof bibs, food-contact materials, and stain-resistant high chair covers. A 2022 Mamavation investigation found PFAS indicators in many popular baby bibs marketed as "waterproof." Choose silicone bibs, untreated cotton bibs, or PFAS-free certified options. Avoid microwaving food in packaging that may contain PFAS (fast food wrappers, microwave popcorn bags). Use glass or stainless steel for food storage.
12-24 months
Toddlers who explore the environment extensively may encounter PFAS through treated carpets, upholstered furniture, and outdoor clothing. Water-repellent jackets, snow pants, and stain-resistant play mats frequently contain PFAS. Where possible, choose untreated natural fabrics. For outerwear, look for brands that have committed to PFAS-free production. Regular hand washing before meals reduces oral exposure from contaminated surfaces.
All ages
PFAS are also found in some drinking water supplies. The EPA set enforceable limits for six PFAS compounds in drinking water in 2024 (4 parts per trillion for PFOA and PFOS). Check your local water quality report at ewg.org/tapwater or contact your water utility. If your water has elevated PFAS, a reverse osmosis or activated carbon filter can reduce levels. Do not boil water to remove PFAS — boiling concentrates them. The situation is evolving as more states pass PFAS bans on children's products.
What Should You Do?
When to take action
- Feeling overwhelmed by chemical safety information — the landscape is complex and evolving
- Not being able to replace all baby products at once — prioritize items that contact food or skin for extended periods
- Using some products that may contain PFAS while taking steps to reduce overall exposure
- Finding it difficult to identify PFAS-free products — labeling is not yet standardized
- You live in an area with known PFAS water contamination and want to discuss testing or filtration
- Your child has unexplained thyroid issues, immune system problems, or developmental concerns and you suspect environmental exposures
- You want guidance on prioritizing which products to replace first
- You discover your drinking water has PFAS levels above EPA limits — switch to filtered water or bottled water for formula preparation immediately
- Your child has ingested a product containing PFAS (such as chewing on a waterproof bib) and is showing symptoms like vomiting or rash
- You have been notified of a PFAS contamination event in your area affecting drinking water

Related Medical Concerns
Heavy Metals in Baby Food
Trace amounts of heavy metals (arsenic, lead, cadmium, and mercury) have been found in many commercial baby foods, including rice-based products, fruit juices, root vegetables, and teething biscuits. These metals occur naturally in soil and water and can accumulate in food crops. While the levels found are generally low, chronic exposure during early development is a concern. You can reduce your baby's exposure by offering a varied diet, limiting rice-based products, and choosing a diversity of grains and produce.
Lead Exposure Concerns in Baby or Toddler
Lead is a toxic metal that can cause serious developmental problems in children, even at low levels. There is no safe level of lead in a child's blood. Children under 3 are most vulnerable because they put everything in their mouths and their developing brains are especially sensitive to lead's effects. The most common sources are lead paint in homes built before 1978, contaminated soil, lead in water from old pipes, and imported toys or pottery. The AAP recommends lead screening blood tests at ages 1 and 2 years. Lead exposure is preventable.
Air Quality and Baby Health
Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
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.
