Just a quickie....Liam's poos have gone from being a light brown watery sticky poo with little lumps to the same consistancy but now a yucky green colour. Is this normal or should i be cooncerned. He has been having what seems like belly paind since the colour change a few days ago and can sometimes be alot harder to settle or won't sleep at all. I have been eating "normal" food and nothing out of the ordinary.
