Hello. Thanks for the query.
Green stool will be normal in a child in which you have started weaning , especially if it contains
iron supplements and even formula milk which contains iron.., eg cerelac with iron ,which is given after 6 monthsof age. If the child doesn't have
diarrhea, mucus in stool, very foul smell in stool, if child is gaining weight and passing urine, probably there is no infection and stool colour will change with diet.
keep modifying diet, introduce, egg white, carrots, apples , et, all cooked and mashed along with the regular rice and porridge( kanji).
However if you are still worried after diet change and child looks ill, take him to the doctor again. Hope you are reassured.
Take care.
