Holidays with a baby: travel, germs, and introducing allergens

Introducing peanut and egg, the current guidance

Research changed the advice. Introducing common allergens early, rather than delaying them, lowers the chance a baby develops a food allergy. NIAID guidelines recommend introducing peanut foods early in the first year.

For most babies, you can start common allergens at home around 6 months, once your baby is developmentally ready for solids, and not before 4 months. Introduce one new allergen at a time, a few days apart, so you can tell which food caused any reaction.

Babies with severe eczema, an existing egg allergy, or both are at higher risk for peanut allergy and should be evaluated by a clinician before peanut is introduced, ideally starting between 4 and 6 months. Talk to your pediatrician first if this describes your baby.

Why the holidays are a tricky time to start

A noisy gathering far from home is not the ideal place for a baby's first taste of peanut or egg. If a reaction happens, you want to be somewhere calm where you can watch your baby and get help quickly.

Introduce a new allergen earlier in the day, not right before bed, and on a day when you are not traveling, so you can observe for a couple of hours. Most reactions appear within minutes to a couple of hours.

Resist relatives offering bites of everything at once. Stick to one new food at a time even during the holidays, and keep already-tolerated foods on the menu so your baby still gets variety.

Holiday choking foods to avoid

Many holiday foods are choking hazards for babies and toddlers. Never give whole peanuts or tree nuts to a child under 5; the allergen-introduction benefit comes from smooth peanut butter thinned with water or breast milk, or peanut puffs, not whole nuts.

Serve allergens and other foods in safe forms. Thin peanut butter so it is not a thick glob, offer well-cooked egg in soft pieces, and cut round foods.

Keep an eye out for the usual culprits on a holiday table.

• Whole or chopped nuts, including on top of desserts and salads
• Whole grapes, cherry tomatoes, and other round foods unless quartered
• Hard or raw vegetables and chunks of apple
• Popcorn, hard candy, and marshmallows
• Hot dogs and sausage unless cut into small, non-round pieces
• Sticky globs of peanut butter and large spoonfuls of any thick food

Travel and germs

Holiday travel means crowds, new surfaces, and lots of people wanting to hold the baby, all during respiratory season. You cannot avoid every germ, but you can lower the load.

Wash hands often and ask others to wash before holding the baby, keep a young infant out of crowds when you can, and avoid contact with anyone who is obviously sick. For newborns, it is reasonable to ask people to skip kissing the baby's face and hands.

Make sure protections are in place before you go: the yearly flu vaccine for everyone 6 months and older, RSV protection for infants, and COVID vaccination per current guidance. Bring your baby's safe, already-tolerated foods so you are not relying on the holiday spread, and pack any prescribed allergy medicine or epinephrine.

Common questions

When should I introduce peanut and egg to my baby?

For most babies, start common allergens at home around 6 months, once your baby is ready for solids, and not before 4 months. Introduce one allergen at a time a few days apart. Babies with severe eczema or egg allergy should be evaluated by a clinician before peanut, ideally starting between 4 and 6 months.

Is it safe to introduce a new allergen during holiday travel?

It is better not to. Introduce a new allergen on a calm day when you are not traveling, earlier in the day rather than near bedtime, so you can watch your baby for a couple of hours and get help quickly if a reaction occurs. Save first tastes of peanut or egg for home.

How do I safely give my baby peanut?

Use smooth peanut butter thinned with water or breast milk, or dissolvable peanut puffs, not whole or chopped peanuts, which are a choking hazard under age 5. Offer it earlier in the day, one allergen at a time, and watch for any reaction over the next couple of hours.

What holiday foods are choking hazards for babies?

Whole or chopped nuts, whole grapes and cherry tomatoes, hard or raw vegetables, apple chunks, popcorn, hard candy, marshmallows, hot dogs unless cut into small non-round pieces, and thick globs of peanut butter. Cut round foods small and serve allergens in safe, soft forms.

Does introducing allergens early really prevent food allergies?

Yes. Research shows that introducing common allergens like peanut early, rather than delaying them, lowers the chance a baby develops a food allergy. NIAID guidelines recommend introducing peanut foods early in the first year for most infants.

How can I keep my baby from getting sick during holiday gatherings?

Wash hands often and ask others to wash before holding the baby, keep young infants out of crowds, and avoid anyone who is obviously sick. Make sure flu, RSV, and COVID protections are in place before traveling, and consider asking people not to kiss a newborn's face or hands.

What should I do if my baby has an allergic reaction to a new food?

For mild symptoms like a few hives around the mouth, watch closely and contact your pediatrician. For any sign of trouble breathing, swelling of the face or lips, vomiting, or a child who seems unwell, call 911 and use prescribed epinephrine if you have it. Discuss an action plan with your clinician beforehand.
