Mom Guilt for Toddlers Allergies

Hi all. I am just seeking any advice/words of encouragement.

About two months ago, my son had an anaphylactic reaction to Sesame. Thankfully, he was ok after a trip to the ER, epinephrine, and steroids.

We took him to the allergist and the sesame allergy was confirmed and honestly, I felt at peace because he has always struggled with eczema and I always suspected he had a food allergy, but I couldn’t identify what it was.

Fast-forward to two days ago when my toddler wanted to have a Larabar (dates and cashews) for a snack, and within a few minutes he had a rash surrounding his mouth/cheeks and swollen lips. Thankfully things didn’t escalate, but I am just really dwelling on this and feeling so bummed and overwhelmed to know he has additional allergies.

I was able to schedule an appointment with the allergist next week, so hopefully he can be tested for all tree nuts and we can confirm the cashew allergy.

I have been reading that tree nut allergies are typically lifelong allergies and I just can’t help but blame myself for not introducing allergens earlier or as frequently/consistently as I should have. I also have an 8 month old, and while I know early exposure is best, it’s hard to not feel so paranoid about introducing allergens after what we are going through with my toddler.

As I said I am just hoping for some words of encouragement or any advice from others going through something similar.

Thanks in advance!
