You are welcome to ask a question any time.

Make sure all the nuts are stored in sealed containers, if his allergy is airborne. Air out the house and make sure prep utensils, cutting board, glasses, plates and flatware are cleaned well. Use a dishwasher if you have one with the heated dry cycle. I have friends that use paper and plastic with guests who have allergies. Read ingredients and manufacturing warnings carefully. Clean the table before he comes. You might want to consider having a rule on where nuts can be eaten in your house when your nephew is not there. This could lessen the area that can be contaminated.

If nuts have been served that day make sure that hands and face are washed. Teeth are brushed. If the allergy is extreme discourage kissing and hugging (if nuts have been eaten in the last 24 hours).

You don't mention how old your nephew is. Each child is different. Some children learn to ask early. Others rely on others for a longer period of time. Eventually they all learn to ask on their own.

Be careful that you clean keyboard if he will use it. My husband ate walnuts while working on computer. My son played on it and broke out in hives (from the oil left on keys).

First off, anyone who has any concerns about family members with food allergies is welcome! You are responsible for your nephew so good for you for searching out information!

Have you asked his parents what, if any, adaptions they may need from you when he goes to visit? They would be a good source of info for you.

I don't know the severity of his allergy (and remember that this can change at anytime), but if you're really nervous about cross contamination use disposable dishes for when he comes over. Some people with nut allergies will react severely to just a trace of oil leftover on a knife for example. Ensure that all members of the family wash their hands and face, including lips, prior to his arrival in case they have eaten any nut products.

Make sure that you get trained on how to use/administer any medications (auto-injector, antihistamines, etc.) he might need should he start to present with symptoms and know how he's presented in past, it can often give you clues to what to expect if he were to ever react while at your house.

Hope this helps. Don't be scared. With proper education you can all have a relaxing visit!

You ABSOLUTELY belong here! THANK YOU for taking steps to ensure your nephew's safety! The more people educated, the better. When my children were little, I depended heavily on their "village" (family, friends, educators etc.) to help me keep them safe.

With a nut allergy always ask about food before they touch or ingest it. I don't care if people think there is no way nuts could be in it, you would be surprised. I am allergic to citrus and that is in EVERYTHING. It never hurts to ask and most restaurants are awesome if you tell them it is because of an allergy. Read labels on everything you buy.
