On Tuesday of last week, my 10 month old son threw up a lot - no fever - he s had diarrhea ever since. This morning he finally woke up at 8am; he went to bed the night before at 6pm, his normal time. He was awake for one hour, had a 6 ounce bottle which he kept down and no diarrhea, but wet diaper . He was incredibly lethargic, really listless and fussy, just wanted to be held and cuddled. Once again, no fever. What do you think I should be doing?
