Wheat and Gluten Sensitivity in My Toddler
Content reviewed against published AAP, NIH, ACAAI guidelines
Last reviewed:
Digestive issues are common in infants and toddlers. If your baby is experiencing wheat and gluten sensitivity in my toddler, here is what you need to know.
The short answer
Wheat allergy, celiac disease, and non-celiac gluten sensitivity are three different conditions that are sometimes confused. Wheat allergy is an immune reaction to wheat proteins (affects about 0.4% of children and is often outgrown). Celiac disease is an autoimmune condition triggered by gluten (affects about 1% of the population and is lifelong). Non-celiac gluten sensitivity is controversial and uncommon in toddlers. Proper diagnosis requires specific testing, so do not remove gluten from your child's diet before testing, as this makes diagnosis more difficult.
Key takeaways
- Wheat allergy, celiac disease, and non-celiac gluten sensitivity are three different conditions that are sometimes confused. Wheat allergy is an immune reaction to wheat proteins (affects about 0.4% of children and is often outgrown). Celiac disease is an autoimmune condition triggered by gluten (affects about 1% of the population and is lifelong). Non-celiac gluten sensitivity is controversial and uncommon in toddlers.

- Usually normal when: Your toddler tolerates wheat and gluten without any symptoms
- Call your doctor if: Your toddler has signs of anaphylaxis after eating wheat: difficulty breathing, widespread hives, swelling, or vomiting — give epinephrine and call 911
- Varies by age — see the age-by-age breakdown below
“The biggest concern with vomiting is dehydration. Young children can become dehydrated quickly, so it's important to replace fluids. Offer small amounts of an oral rehydration solution frequently.”
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
6-12 months
Wheat and gluten-containing grains are typically introduced during the starting-solids period around 6 months. Current guidelines do not recommend delaying introduction, even in families with celiac disease. If your baby develops symptoms after eating wheat or gluten-containing foods (diarrhea, vomiting, skin rash, or hives), note the reaction and discuss with your pediatrician. Wheat allergy can cause immediate reactions (hives, vomiting within minutes to hours), while celiac disease symptoms develop more gradually over weeks to months.
12-24 months
Celiac disease often becomes apparent during this period as toddlers eat increasing amounts of gluten-containing foods. Symptoms may include chronic diarrhea or constipation, bloating, poor weight gain or failure to thrive, irritability, and a distended belly. Some toddlers develop dermatitis herpetiformis (itchy, blistering skin rash). If celiac disease is suspected, your pediatrician will order blood tests (tissue transglutaminase IgA antibody). It is important that your child continues eating gluten-containing foods until testing is complete, as a gluten-free diet can cause false-negative results.
2-5 years
If celiac disease is diagnosed, your child will need a strict lifelong gluten-free diet. This means avoiding all wheat, barley, and rye products. Work with a pediatric dietitian to ensure nutritional adequacy, as many gluten-free products are lower in fiber, iron, and B vitamins. If wheat allergy (not celiac) is diagnosed, your child may outgrow it — about 65% of wheat-allergic children outgrow the allergy by age 12. Your allergist will guide periodic retesting. Do not put your child on a gluten-free diet without medical diagnosis, as unnecessary restriction can affect nutrition and growth.
What Should You Do?
When to take action
- Your toddler tolerates wheat and gluten without any symptoms
- Your toddler has occasional loose stools that are not consistently related to gluten intake

- Your toddler is not gaining weight or growing as expected despite eating well
- There is a family history of celiac disease and you want to discuss screening
- Your toddler has signs of anaphylaxis after eating wheat: difficulty breathing, widespread hives, swelling, or vomiting — give epinephrine and call 911
- Your toddler is losing weight rapidly, has bloody stools, or is severely dehydrated from diarrhea
- Your toddler appears malnourished with a distended belly, extreme irritability, and failure to thrive

My Toddler Gags or Refuses Certain Food Textures
Many toddlers have strong preferences or aversions to certain food textures, and this is one of the most common feeding challenges parents face. Some children gag on lumpy or mixed-texture foods, while others refuse soft or mushy textures. This is often a normal part of sensory development and usually improves with gentle, repeated exposure over time. However, severe texture aversion that significantly limits food variety or affects nutrition may benefit from evaluation by a feeding therapist.
Strategies for My Picky Eater Toddler
Picky eating is one of the most common and frustrating aspects of toddlerhood, affecting up to 50% of children between ages 2-5. It is a normal developmental phase driven by neophobia (fear of new foods), a desire for control, and a naturally slowing growth rate that reduces appetite. Research shows that most picky toddlers get adequate nutrition over the course of a week, even when individual meals look concerning. Pressure, bribery, and forcing bites typically backfire and can worsen the problem.
Managing My Toddler's Egg Allergy
Egg allergy is one of the most common food allergies in children, affecting about 2% of young children. The good news is that approximately 70% of children with egg allergy outgrow it by age 16, and many outgrow it by age 5. Management involves strict avoidance of egg-containing foods, having an emergency action plan, and working with your allergist to determine if your child can tolerate baked egg products, which many egg-allergic children can.

My Baby's Belly Looks Swollen
A rounded, slightly protruding belly is completely normal in babies and toddlers due to immature abdominal muscles and their proportionally larger organs. However, if the belly becomes suddenly swollen, feels hard and tight, or is accompanied by pain, vomiting, or changes in bowel movements, it needs medical evaluation as it could signal gas buildup, constipation, or rarely, something more serious.
My Baby Has an Anal Fissure (Blood When Pooping)
A small streak of bright red blood on the surface of your baby's stool or on the diaper is most commonly caused by an anal fissure, which is a tiny tear in the skin around the anus from passing hard stool. Anal fissures are very common in babies and toddlers and usually heal on their own with simple measures like keeping stools soft. While this is rarely serious, any blood in your baby's stool should be mentioned to your pediatrician.
Can Antibiotics Damage My Baby's Gut?
Antibiotics can temporarily disrupt your baby's gut microbiome, which may cause loose stools, fussiness, or diaper rash during and shortly after treatment. However, when antibiotics are medically necessary, the benefits of treating the infection far outweigh the temporary gut disruption. Most babies' microbiomes recover within weeks to months, especially with breastfeeding and a gradual return to normal feeding patterns.
