DS who is 2.6 has been sick the last 2 nights. Both mornings (ie yesterday & today)he has woken up and eaten a decent breakfast but then it has gone pretty much straight through and he has turned down all food for the rest of the day. Yesterday he was on good form despite being unwell but today he is much more fed up. Am giving him plenty of cooled boiled water with sugar & salt. He doesn't have a temperature.
This is our first experience of this and am not sure when I should be contacting the DR. Any advice very welcome!
