I m really worried about my almost 2 year old son (Nov. 19th is his birthday). Starting about a week ago I started noticing that he looked like he was coming down with a cold...runny nose, and a bit more irritable than normal. But about 4 days ago his appetite pretty much became non existent. He would attempt to nibble on different things but not really any thing. The only thing that he would willingly take was pedia-lite or milk. But on top of all that, pretty much every time he.drinks a decent amount, he would vomit it back up. And I can tell her is just completely drained of energy at.this point from all the appetite loss and vomiting. He has also had 2 bad diarrhea diapers for 2 of the day s.... he.has a appointment with his primary tomorrow morning but I am just so worried with all the horrible dry heaving/ vomiting...
