Hi, thanks for using healthcare magic
It is possible that she has gastroenteritis
which can present with vomiting
in the absence of diarrhoea
It is important to monitor for any indication of dehydration- decrease urination, dry skin, skin tenting (when the skin is pulled up, it stays in that position), dry mucous membranes, increased heart rate
, no tears when crying)
Because children can become dehydrated quickly, it may be necessary to have her evaluated.
It is important not to give her too much to drink at one time, if her stomach is irritated then she will just vomit it back up.
Give her small amounts (the exact amount is usually calculated by a doctor based on her weight)- the amount may be about a tablespoon for some children, wait 5 minutes, if she does not vomit then give some more.Continue this for about an hr.
If she retains this then the amount can be slowly increased, not too much or she will bring it back up.
It is best to give her pedialyte
or another liquid that would replace the electrolytes she is losing by vomiting.
As stated earlier,at her age an evaluation by her doctor would be best.
Hope this helps,
