Seems to some stomach infection
.Give something like jeelo or ice to suck.avoid solid foods,give her liquids only like juice,soup etc.try anti emetic once again with just dips of water and then do not give anything for next 45 minutes.mostly this will be retained and vomiting
will stop.If you have anti colic
medicines available give her,or at least give tab acetaminophen
this will help to some extent.and when things become ok take her to doctor.
