Thanks for your query.
It is perfectly normal for infants to have up to 8 motions per day. Greenish stools are due to variation in diet, particularly when- during teething- the infant refuses to eat, and subsists on milk only.
Do not worry: the stools will normalize once teething is over. During teething, the infant tries to bite whatever he comes across. It is common for the infant to bite an infected item/toy or the teether.
As such, the stool test
is normal. You have not mentioned if the stool culture was done for bacteria/fungus? In which case, a short course of antibiotics / antigungals will suffice. Encourage the child to eat semi-liquids, such as porridge etc..
