Dd 18 months was very whingey in bed last night. Irritable and kept crying sporadically. Then at about 3am she was sick and felt a bit hot. She went on to be sick a further two times and then finally slept soundly at about 4:30.
When she woke up at 8 she had a horrible, massive, loose nappy but since then she's been fine and in a great mood, even managed some toast.
I'm worried this might be a bug because I'm due to go away with work on Monday for a few days and I can't leave her or other dc if they are unwell or if I get it too 
Would a bug go on for longer than this? She is right as rain now. Pray for me!!
