Thanks for your honest feedback. From personal experience I know we may not be in the clear just yet. Both my brother and I developed allergies to nuts/chocolate/shellfish/milk at an older age (7 and 9). Nothing life threatening, just major rashes every time those foods were eaten. And my best friend ended up in the ER for a major shellfish allergic reaction on my wedding day.
I have health anxiety issues so prior to the allergy test, I was extremely scared and anxious about giving my DD anything that might trigger a severe allergic reaction. The test has somewhat eased my mind, but like you, my DH is still cautious about trying new foods on DD because he's read that there are false positives and negatives.
Since the allergy test, I've given DD a small amount of peanut butter and chocolate. And so far, so good. She seems to react to paint, but how do you stop a 2 year old from painting at daycare? That's how they learn, right?
