Thank you for your query,
You continue soy milk for your child as advised previously.
For G6PD deficiency
, there is no need to change the formula as formula wont effect the child.
In G6PD deficiency, children are prone for hemolysis
due to exposure to some drugs like sulfonamides, antimalarials and some antibiotics.
So you should be careful in giving medications, and inform the doctor about G6PD status before the prescription of medication.
And take a list of avoidable drugs, produts, and chemicals.
Consult your Pediatrician
for feeding advise and education related to drug use.
Hope I have answered your query.
