Thank you for your query.
Did your daughter have only one vomit or a few of them? If it has been only one than you can wait and watch. Give her plenty of small oral fluids which she should retain. In case she vomits again then you can give her ondanseteron 2 ml. to control the vomiting
. It is quite likely she vomited following a throat infection
as you mention she is having cold
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
