Thanks for writing in.
Could you quantify the amount of blood in the vomitus? If it is just streaks, it could be due to retching
and tearing of very tiny blood vessels. Vomiting
might be present due to the urine infection. Is she on antibiotics right now? Please give her plenty of fluids to drink. Bland rice gruel with a pinch of salt should make her feel energetic.
However,I would advise you to take your daughter to the paediatrician as soon as possible to evalute the small red spots /and blood in vomitus .
Hope this helps
