What to Tell a Babysitter About a Child With Allergies (And How to Make Sure They Don't Forget)

When your child has a life-threatening allergy, the stakes of a babysitter not knowing — or knowing but not really understanding — are as high as they get. Telling a babysitter about the allergy in the car on your way out the door is not enough. Information shared verbally under time pressure is processed, retained, and recalled imperfectly.

This guide covers what to communicate, how to communicate it so it sticks, and what to do to make sure she has it accessible when she needs it — not in her head, but in front of her.

Start with severity — not just the allergen

Parents often say "he's allergic to peanuts" and consider the communication done. The babysitter hears this and forms her own model of what an allergic reaction looks like. She may be thinking about the time she got hives from strawberries. She is not picturing anaphylaxis.

The first thing you communicate is the severity, in explicit terms:

• Life-threatening / anaphylactic — can cause throat swelling, loss of consciousness, death if untreated. EpiPen required. Call 911.
• Severe — significant systemic reaction. May require antihistamine and medical evaluation. Know the threshold for calling you versus calling 911.
• Moderate — uncomfortable, possibly distressing, but not life-threatening with normal response.
• Mild — localized reaction, manageable without emergency intervention.

Use those words. "Life-threatening" lands differently than "really bad."

Tell her what the reaction looks like

A babysitter who has never witnessed an allergic reaction does not automatically know what one looks like. Describe what she might see:

• Hives or rash, particularly on face, neck, or trunk
• Swelling — especially of the lips, tongue, or face
• Difficulty breathing, wheezing, voice changes
• Vomiting or stomach pain starting shortly after exposure
• Dizziness, pale skin, or unusual fatigue
• Your child complaining that their throat feels "scratchy" or "tight" — this is serious

Early symptoms can escalate quickly. She needs to know that a "scratchy throat" comment is not a casual complaint — it is a signal to act.

EpiPen protocol — be specific, not general

If your child has an EpiPen, the babysitter needs more than "it's in the bag." She needs:

• Exact location — which bag, which pocket, and whether there is a spare
• When to use it — "if she seems to be having a reaction" is not precise enough. Define the threshold: swelling, difficulty breathing, hives plus other symptoms?
• Whether to call you first or use it first — for most life-threatening allergies, the protocol is: use the EpiPen, then call 911, then call you. But some families have different protocols. Be explicit.
• How to use it — do not assume she knows. Show her. Walk through it once. EpiPens are intuitive but in a crisis moment, unfamiliar equipment fails.
• What happens after — even if the EpiPen resolves the immediate reaction, she must go to the ER. EpiPen effects wear off. Secondary reactions occur.

Hidden sources and cross-contamination

This is where many allergy communications fall short. A babysitter who knows your child is allergic to peanuts will not give him peanut butter. But she might not know about:

• Shared-facility manufacturing — "may contain" warnings on packaging
• Cross-contamination in restaurant kitchens — sesame oil, shared fryers, utensil contamination
• Hidden ingredients — soy sauce (wheat), pesto (pine nuts or other tree nuts), mole sauce (peanuts), many Asian sauces
• Non-food sources — certain lotions, soaps, and art supplies contain nut oils
• Airborne exposure — in rare severe cases, being near someone eating the allergen can trigger a reaction

The specific risks depend on the allergen and the severity level. Tell her the rules for your child specifically — not generic allergy advice.

The "when in doubt" rule

Give your babysitter a single clear rule for uncertainty: if she is not sure whether something is safe, it does not go in front of the child. No exceptions. No trying to read the label. No "probably fine." The rule eliminates the judgment call.

Why telling is not enough

Here is the uncomfortable truth: even if you have this conversation perfectly, your babysitter will not retain all of it with perfect accuracy. Under stress — a toddler crying, the child complaining of stomach pain, trying to read the back of a package — she is reconstructing the conversation from memory. Details get compressed, thresholds get fuzzy.

What she needs is the information in front of her. Not in her head. In writing, organized, accessible on her phone.

The babysitter information that protects a child is the kind she can check at the moment she needs it — not the kind she recalls from a verbal handoff.

What the written record should include

For every allergy:

• Allergen name (and common alternative names or sources)
• Severity in plain terms
• What the reaction looks like
• What to do at first signs of exposure
• Location of EpiPen and how to use it
• Whether to call you first or call 911 first
• Foods to avoid (with specific examples of hidden sources)

And critically: the allergy information should be at the top of whatever she has access to — not buried after bedtime and pickup instructions. In an emergency, she will not search.

Baton Pass is designed around this constraint. Allergies are always first, sorted by severity, in red. A babysitter opening the link on her phone sees the allergy information before anything else. Life-threatening allergies cannot be scrolled past. That is not a design preference — it is a safety requirement.

The conversation on the way out the door

Even if you have given her written information in advance, do a 30-second verbal confirmation when you leave:

• "You have the link I sent you, right?"
• "The EpiPen is in the front pocket of the blue bag on the counter."
• "If he has any reaction — hives, stomach pain, anything — call me immediately. Don't wait."

This is not redundant. The verbal confirmation in the moment anchors her awareness in a way that a text sent the day before does not.

After the shift

Ask about the evening. Not just "how was it?" but specifically: "Did he eat anything you weren't sure about?" A babysitter who knows you will ask is more careful throughout. It also gives you the chance to catch a near-miss before it becomes a recurring pattern.
