My doctor said it was okay to introduce my one-year-old to peanut butter. Are there any tips on how to go about introducing a food that may cause an allergic reaction? I remember hearing it's best to introduce these types of foods in the morning so the reaction doesn't appear overnight when the baby isn't as visible. Also, I know it often takes more than one exposure to trigger a visible reaction. Is there a recommended amount for a first exposure? At what point do I relax and decide he's (hopefully) not allergic?

+1 Good question. I've been thinking about this too.

My doctor told me that allergic reactions don't always appear the first time the food is introduced. Based on the answers below, it sounds like this hasn't been the case for several of you. Have any of you had cases of introducing a food several times before discovering your child is allergic? Basically, I'm wondering if I can relax if my toddler doesn't react the first time he eats peanut butter.

We struggled with sensitivity issues (not severe allergies) a lot with my first daughter. We found that spreading a little of the potential allergen on her cheek would often work pretty well.

If you're concerned your 1yo will eat the peanut butter before the test is finished (10 minutes?), you can apply it to the back instead.

I guess that's pretty much a skin test, though we didn't scratch the skin first.

My youngest had a bad reaction to peanut butter when she was about 10 months old so kept her off it until recently. The day I decided to re-introduce it I just made her a sandwich with it on, had the antihistamine on standby and hoped for the best. Also made sure my paeditrician's number was close at hand.... I agree about doing a "skin test" first, thats how I discovered my little one was allergic. Thankfully she has outgrown it.

My eldest is allergic to peanuts, so we have put some thought into this. The skin test method is a good one, but it is not foolproof - the prick test with a control will give more accurate results. Have you considered seeing an allergist if you are really nervous? Also - I agree with Michael, the back is the safest location to ensure that it doesn't get consumed!!

The other precaution that I can offer is to familiarize yourself with the signs of anaphylaxis. has a pretty good list. Otherwise, know where the closest emergency room is, you might want to make sure that you access to a children's antihistamine (we use liquid benadryl) or if possible, someone with a children's epipen, which is a smaller dose than the adult one.

I'm the one with life-threatening allergies in my family, so I may have a different perspective on this one. I didn't develope allergies until I was an adult and none of my kids have any. So, I tend to have the view that you just can't worry about it until it shows up, but to have antihistamines on hand at all times just in case. (Sort of the "trust in God, but lock your door", point of view.)

I've introduced foods that may (and remember that's a big may if neither you or your husband have allergies) cause allergies in the morning for 3 or 4 days running and then just added it to their diet in a normal rotation kind of way.

Allergies can show up to the strangest things at pretty much any time, so, really, try not to worry too much, what helps me is to keep a tiny bottle of childrens benadryl in the diaper bad. It's kinda like a little magic talisman that I hope I'll never have to use. (It's right beside my benadryl!)

I suspect the approach may vary depending on whether your children have prevously had allergic reactions. After discussion with the child health nurse at my son's 15 month check I introduced peanut butter. He had never previously shown any allergic reactions to any other food. I gave him it mid morning in a sandwich. I made sure I was sure I knew where the phone, my keys and bag were in case we had make a qucik trip somewhere. I think I did it when my husband was around as well.

He had no reaction and peabut sandwiches are one of his favourite foods. I suspect my daughter's first taste of peanut butter was when her brother gave her his crusts, something I would rather he didn't do.
