16 month ds threw up in the middle of the night the night before last, and then ate nothing yesterday save one piece of toast. He threw up badly last night and had a temperature all last night tho slept ok. His temp is down today but still a bit hot and refusing to eat. Any ideas on what to do? He is sipping water and breastfeeding a bit but that's it. Wonder if i should take him to docs tho he seems fairly happy but low key today.
