Yes, it is normal. My son is 5 months old now and he is also drinking Wakodo NB milk. He has poopoo everyday. Doctor says there is no any health problem if the colour of poopooo is greeen.
Thank you muichumum!
His poopoo used to be yellow in colour. Only starting from last friday, he got the green poopoo and makes me so worry!! What about your son? Always gets dirty green poopoo or just happens from time to time??
