my daughter had tummy ache all day on tuesday and started being sick at 10 pm at night, she was still being sick the next day even just drinking water, took her to the doctors and he just said it was a bug, she had some dry toast on thurs morn, and brought that straight back up, today she has eaten some dry toast and kept it down, she keeps saying she fells unwell, but have noticed that her lips are blue - is she ok???
