How To Introduce Shellfish and Fish To Your Baby

April 20, 2021 4 min read

Shellfish and fish are two of the most common allergies in adults and children. Though they tend to affect more adults than children, for those who develop it in childhood, it is considered a lifelong allergy and most will not outgrow it. 

Shrimp is considered the most common shellfish allergy, while alternatively cod, salmon and tuna are the most common allergies in finned fish.

As with other allergies, a shellfish or fish allergy can be severe, but thanks to landmark clinical studies, we now know that introducing babies to these allergens early and consistently, before they turn one, is essential. 

When To Introduce Shellfish and Fish To Baby

Shellfish and fish in a safely prepared format may be introduced as soon as a baby is ready to start solids, along with most other allergenic foods, around 4-6 months of age according to the 2020 USDA Dietary Guidelines.

The American Academy of Pediatrics states that "within a few months of starting solid foods, your baby’s daily diet should include a variety of foods each day that may"

Introducing shellfish and fish early and often is essential in helping to prevent this allergy and reduce stress later in life. 

How To Introduce Shellfish and Fish to Baby

When introducing any fish or shellfish meal to your little ones, it is essential to make sure it is fully cooked and always checked for bones or bits of shells. Toddlers should never eat raw or undercooked fish or shellfish. Furthermore, the rubbery texture of shellfish can be difficult for children to break down, and should be fed in a safe format. 

Not only are fish and shellfish a common allergen, but they also have a unique flavor and chewy, slippery texture that your child will have to become adjusted to. 

Is your baby ready for their first taste? Here are three of our favorite ways to introduce shellfish and fish to your baby for the first time:

  • Homemade Recipes
  • You can offer thinly sliced or minced cooked shrimp or fish to children alone or alongside other foods. For shellfish, remove the tail and shell first. As they age and become comfortable with chewing and eating other finger foods, you can serve whole shrimp or prawns to eat as finger food or on a fork.

  • Early Allergen Introduction Powder
  • Food allergen introduction powder, like SpoonfulONE’s Mix-ins, is an easy and safe way to introduce your little one to shellfish, fish, and other allergenic foods starting as early as 4 months. These powders can easily be added to breastmilk or formula and bottle-fed, or even mixed into purees, applesauce, or oatmeal.

  • Early Allergen Puffs
  • As your child ages, you can transition from allergen powders to more solid Puffs. SpoonfulONE Puffs are a nutritious baby snack designed to easily dissolve with saliva and are the perfect finger foods for growing infants. A perfect on-the-go snack that includes the 16 foods most commonly associated with over 90% of food allergies*, Puffs are recommended for babies at least 6+ months or older. If you are wanting to add more savory flavors to your little one's growing palate, try Crunchy Puffs, a delicious puff snack with three yummy savory flavors. 

    What’s The Difference Between Fish and Shellfish

    There are two types of shellfish: 

    • Crustaceans, like crawfish, crab, lobster, and shrimp; and
    • Mollusks, like clams, mussels, or scallops. 

    Though crustacean allergies are more common, babies with any shellfish allergy are more likely to experience reactions to other shellfish. 

    Fish families include types such as salmon, tuna, catfish and cod. Due to high mercury levels, the FDA recommends avoiding introducing shark, swordfish, king mackerel, and tilefish to your little ones. Instead, fish types including salmon, cod, shrimp or canned light tuna are best. 

    Shellfish allergies have a higher prevalence in children, affecting up to 1.3% of children, while fish allergies affect .6% of the population. An allergy to shellfish does not necessarily mean your child will also develop an allergy to finned fish, as they are not closely related. 

    Why SpoonfulONE’s Mix-ins for Early Allergen Introduction 

    At SpoonfulONE, it’s our mission to create a safer and more convenient way to introduce children to shellfish, fish, and other food allergens early and consistently. This comprehensive system of delicious baby snacks is designed to be given to your baby starting as early as 4+ months. 

    • Safety -We used landmark research like LEAP and EAT to inspire our science, but we didn’t stop there. Our founder, Dr. Kari Nadeau, the Director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford University, invested in and conducted her own proprietary research. This research showed that the diverse mix of ingredients in SpoonfulONE, precisely portioned to ensure safety, helped increase IgG4 (protective antibodies) in children after feeding SpoonfulONE for a year.
    • Comprehensive - The most complete early allergen introduction* program, SpoonfulONE includes the 16 foods responsible for over 90% of food allergies. Each packet contains a gentle amount of peanuts, milk, shellfish (shrimp), tree nuts (almonds, cashews, hazelnuts, pecans, pistachios, and walnuts), egg, fish (cod and salmon), grains (oats and wheat), soy, and sesame.
    • Convenience - When you introduce a multi-allergen routine to your infant, the preparation of each ingredient every day can take up a ton of time. SpoonfulONE helps give you your time back. Our system helps eliminate the fear, confusion, and guesswork out of introducing new foods to babies.

    The Bottom Line: Although very important, shellfish and fish are just two of the 9 food groups associated with over 90% of food allergies. Unlike other products on the market that only cover peanuts, milk, or eggs, SpoonfulONE is a comprehensive and revolutionary approach to early allergen introduction.
