sick baby

Well Bruce has been sick since Saturday evening, with cough, at first dry heaving(dont know if I spelled that right) then the vomiting started later. It got really bad to where he was throwing up water...anyways I took him to the ER and had him checked out and honestly they really didn't tell me what his problem was. I was there from 10pm on saturday to 1am sunday, I HATE THE ER! anyways, we got there and they checked his temperature-which was fine, pulse-which was fine, and then they gave him this Zofran stuff to help with the nausea which went all of the floor and the bed right after giving it to him. We had to wait for awhile to see how he does with what meds went in his system, he did fine and no more vomiting. So they finally release us and get home and he throws up some more, we have to change his pj's and put him in bed, I slept on his floor so I can hear him if he needs anything. The next day the poops start...(poor kid), and the vomiting is still happening of course, no fever. I called his doctor to find out what needs to happen without having to go the Idiot farm (ER) again, and he said "just give him some pedialyte and keep him hydrated and keep your eye on him, if he gets worse take him back to the ER, if he doesn't get better but not worse call me on monday morning and I will examine him." Well today Monday, he is doing much better no throwing up, yes he still has the poops, he is very unhappy, (do you blame him?) I am still trying to decide if it is necessary to still have his doctor examine him or not.
