<human>: very dark green stool in 16 months old baby, very gassy, unsettle, been told he is lactose intolerant, changed his milk to soy milk for last 2 months, he still breastfeeds as well, sometimes he is got 2 stools a day, sometimes 3, sometimes 1, nothing regular....
<bot>: Thank you for your query. There are different causes of green stool at babies:-changing of formula;-symbiosis;-color of cleaved protein;-salmonellosis;-stool can be changed to green color due oxidation if we have not changed diapers for a long time.  I suggest--check stool analysis;-stool culture for symbiosis and sensitivity to antibiotics-you can give eco norm for 3-5 days, then baby lac for 1 month for normal intestinal flora Take care Wishing to your baby and you are good health
