I am really sorry to see that your child is suffering from jaundice
loss of appetite i.e not taking food & vomiting
always go along with jaundice. regarding diet what you are giving now is right. you can add yoghurt, lassi, tender coconut water also.
since child is having fever up to 102 F, jaundice could be due to infective causes like malaria, typhoid, lepto, hepatitis A
. thus he needs definite evaluation by a pediatrician
and antibiotics if needed.
just keep in mind red flag signs like bleeding, drowsiness
,seizures and multiple episodes of vomiting report immediately to emergency.
although appetite may take some time to recover keep giving him small quantities of above said diet, child will get well soon.
