He's had a d+v bug and didn't keep fluids down for nearly 48 hours. He seemed to pick up a bit yesterday after a shaky start and has been keeping food and water down since. He had breakfast this morning and has been sleepy all day. I've offered him drinks regularly which he has been taking but he's not been drinking huge amounts.
DP took him to the doctors who have sent him to the hospital. what should I expect?
