I wish your daughter a quick recovery, @emmamia !
Children do not tolerate adaptation in a new climate for them!
And swimming in the pool could have had a little effect!
The body has not yet adapted to the weather conditions!
Yes, and the food is new!
More let them water simple,
not soda!
And while you should avoid eating fruits!
think. that everything will be back to normal soon.
And I recommend to give 1-2 tablets of activated charcoal!
It normalizes the work of intestine.
Thank you for all your suggestions and wishes. I tried to follow your suggestions, and she is feeling a bit better now. I am sorry for such late reply, but I was too tired to write any comment when she was feeling so sick as she did.
I didn't found the activated charcoal, but I gave her some probiotics. I will try to find them at our pharmacy for the next time anyone will have such problems.
