Dr. Waserman: Daffodils are considered “allergy-friendly,” since plants with showy flowers are generally pollinated by insects rather than the wind. Daffodils produce less pollen, and symptoms such as allergic rhino-conjunctivitis and asthma aren’t commonly associated with them.

However – handling daffodils is another story. Among florists and flower pickers, allergic contact dermatitis, irritant contact dermatitis (from sap) and hives are quite common.

Your daughter may have had an allergic or irritant contact dermatitis reaction or urticaria (hives). I recommend that she not handle daffodils and related narcissus varieties.

While unusual with daffodils, the throat symptoms might be an acute reaction, or anxiety as you suggest. Your daughter needs to be assessed by an allergist. If her symptoms and testing indicate allergic rhinitis, the allergist likely will prescribe intranasal steroids to alleviate the allergy.

Dr. Waserman: Having allergic parents does place your son at higher risk of becoming allergic. However the particular allergies he may develop are not predictable.

Even though you are breastfeeding, unless you have been on milk avoidance yourself, he has probably already been exposed. I would introduce milk at the recommended time.

A cautious way to do so would be to place a drop on your son’s face, wait 10 minutes to see if he develops any redness or swelling,  and then increase to two drops on his lip, also waiting and observing for any reaction.

You can then slowly increase his exposure over 1-2 days. If you are anxious, skin testing by an allergist to determine his allergic status can also be done. It will delay the process, but will let you know one way or another. Good luck!

Dr. Waserman: Oral allergy syndrome is seen in birch tree or ragweed pollen allergic individuals  who may develop symptoms on ingestion of certain raw fruits, vegetables, or tree nuts.

Symptoms typically consist of itching, tingling or  swelling of the mouth, lips, and throat. An allergic reaction happens when the foods are eaten raw. Once the foods are cooked, they can be eaten safely.

Jams are prepared by heating the particular fruit. If you experienced symptoms after peach jam, you may have a true food allergy to peach, and not just an oral allergy syndrome. I highly recommend consultation with an allergist for assessment and skin testing to help sort this out.
