My little dd (nearly three) was sick at five a.m on Thursday morning,nothing else happened for ages,she seemed fine,and then bad diarrhoea at about 3.p.m. seemed ok again, then vomited at bedtime.Slept through Thursday night,normal poo Friday afternoon,thought she was better but then looked much more ill again at suppertime, more Diarrhoea and vomiting at bedtime,so more than 24 hrs later.Up a few times in the night,last at 2 a.m. then nothing more.Off colour today but eating a bit (e.g. ricecakes) nothing from either end again until bedtime when her temp went up (as it had last night ) and she was very sick again.She is asleep now but gut is gurgly and I think she may be up again.Is this usual,to go 16 or even 24 hours and then have more vomiting or diarrhoea? Do bugs like this go on and on? I have been lucky as my older DD is five and I have never had to deal with the runs,and only twice with puke!
