DD1 (4yo) was poorly at the beginning of the week, vomiting all night on Monday night and during the day Tuesday. Wednesday morning she was fine during the day, but said she had a tummy ache come evening. And every day since, she's a picture of health with a normal appetite during the day, but come 4pm she starts complaining that her tummy hurts and gets gradually worse during the evening. She won't eat her dinner, passes out on the sofa (which she never usually does) and cries her little heart out. On Thurs I thought it was all an act to not go out dog walking and stay home and watch TV instead, so I dragged her out walking anyway but when we got home she threw up and passed out on the floor! (I felt dreadful!)
Right now she's in bits upstairs, howling while DH tries to get her bathed and off to bed, and she hasn't eaten her dinner again.
I'm at a loss as to what this could be, since she's absolutely fine all day and in so much pain after 4pm, and it's been going on for nearly a week.
Any ideas?
