My daughter (4) has been complaining of tummy ache for about 10 days, I've kind of ignored it as she likes to moan about stuff like that
(I feel bad now)!
So, on Sunday she vomited all her breakfast up, but was fine after. Then for the last two days she has had very loose bowels, almost like baby poo colour and frothy/bubbly?
This morning she cried going to the toilet and became very upset, but was then OK. However, tonight she ate the last mouthful of her dinner, and came running into the kitchen literally shaking all over, like a convulsion (I know it wasn't). She was hysterical and couldn't tell me what was wrong, then she needed to go to the loo urgently, and passed another loose poo?
She sat on my knee for 10 minutes and was dithering and her teeth were chattering. I immediately phoned the doctor and they told me to take her OOH.
Doctor saw her, did pulse, heart, temp and checked her tummy and couldn't really say what was wrong. He said she is obviously not right, and thought it might be colic pains? I appreciate its difficult to diagnose as she had perked up a bit? 
Is it worth another visit to my own GP in the morning, or should I just leave it?
Also, do you think it might be emotionally related, we are having contact problems with her daddy at the moment, he has let her down a lot recently and I know she is very distressed about it all?
Doctor also said to starve her for 24 hours, how does that work with a 4 year old?
