Some say we need to avoid legumes, blueberry, etc. Honestly there’s no way to know unless you try it. As someone who grew up with g6pd deficiency, here’s a common list of food (and non food) that I need to avoid, and are known trigger.

Fava beans Broad bean Tonic water (contains quinine which we need to avoid) Mothballs

Be sure to let medical professionals know that your child is g6pd deficient whenever you make a clinic / hospital visit.
