Okay, for the last couple of days my 5 month son has had some diarrhea. Really bad smelling diarrhoea! I have only fed him milk for the last two days, the day before that he had solids. It seem's that he's processing the milk too fast. I'm a bit worried, as this is the first time he's had diarrhoea. I am not sure if he's sick or he's just processing it too fast. He seem's to be fine apart from that: No screaming or playing up.. He has a few coughs here in there.. But it's nothing severe. Please help!
