Many parents know they should introduce allergens. Few know what comes next.
Parents are hearing more than ever about introducing peanut, egg, sesame and tree nuts early. But after that first successful taste, many families ask the same question: How do I keep feeding them consistently?
Busy schedules, picky eating, travel and everyday life can make it surprisingly difficult to keep multiple allergens in the weekly routine. That’s exactly why GrowHappy was created.
Developed by Pediatric Allergy, Nutrition & Gut Health Experts
GrowHappy was designed to make both allergen introduction and ongoing allergen maintenance simpler for busy families.
Their Allergen ImmunoButters are a meal or snack for babies that provide dosed top allergens with other fruits and veggies to support diet diversity. They include:
- Whole-food nut and seed butters
- Science-backed 2g allergen protein dosing
- 1 Top Allergen per flavor (Egg, Peanut, Cashew, Sesame, Walnut)
- 16 plant-based ingredients for gut health
- Ready in 30 seconds
- Co-founded by the experts who wrote the US, EU and Canadian Allergy Guidelines

GrowHappy recently launched their Allergen ImmunoBars, an easy snack for toddlers and older kids designed to make continued allergen exposure simple, delicious and mess-free. Available in Peanut, Mixed Tree Nut and Sesame, each ImmunoBar includes:
- 3 flavors that separate top allergens (Peanut, Sesame and Mixed Tree Nuts)
- Measured allergen protein in every bar
- Whole nut or seed butters, whole grain oats and real fruit
- Plant-based ingredients and fiber to support gut health
- No added salt or sweeteners; never ultraprocessed
Why “Often” Matters
Once a child safely tolerates an allergen, many clinicians recommend continuing to include it regularly as part of the diet. Parents should always follow guidance from their pediatrician or allergist. For many families, consistency is the hardest part. GrowHappy was designed to help make that habit easier.
A Note for SnackSafely Families
GrowHappy should not be used to introduce foods that a child has already been diagnosed as allergic to. Many families use GrowHappy to help maintain regular exposure to allergens that are already safely tolerated, or with younger siblings beginning solids under the guidance of their pediatrician or allergist.
