Has anyone else's little ones had adverse affects to these? My little boy had the fever, as expected but he's been really sleepy like falling asleep on my boob and generally seems less alert. He had a weak cry and seemed really in pain. Belly has been gurgling and he has been having milk diarrhoea, lots of farts and vomiting. Are these normal enough and other people have experienced this or should I get him seen by his doctor?
