My daughter is 21 months old. Yesterday, she had a nappy with quite loose stools in and there were bits of green in it. I changed her nappy about an hour and a half ago and it was another bad nappy, this time, all of her loose stools were green. She hasn't eate anything that could have turned it green but I'm quite worried about this. She is normal in herself, is still active and boisterous and happy, and the only problem is the green poo.
