I was told any formula is ok for g6pd babies as milk doesn't really interfere or not supposed to cause problem. My boy has g6pd and has been drinking Nan HA and no problem so far. If baby keeps vomitting it cld be due to other things such as acid reflux or baby isn't feeling well so u may want to bring him to the doctor.
My girl also has G6PD. Further consult with the PD she had acid reflux hence ia now consuming AR formula. Her reflux has since reduced significantly
Thanks for sharing! Will followup with pd too if it is presistant
