Not too sure what to think

I took Kenny to the ER today. He's been having his eyes going downward, looking like a sunset at times. And after talking to a friend whose daughter has hydrocepholous and the symptoms, I decided to take him in. He's been acting strange these past couple of days. Puking more, (even though he's on reflux meds), crabby when he's up, waking up crying like someone has just pinched him, and just not himself. The dr in the ER said that he looks fine, and we upped his reflux meds. I somehow am not convinced. I guess I'm just too worried now. I'm not that kind of parent to be paranoid though. So when I do worry, I know that most would have had their kid in ten times faster than me....well that's not really true, but you get the idea. I don't run to the dr with every runny nose. I go when the kids need to, or my 'mother's' instinct tells me, OK GO!!! I'll try to sleep these next two nites, and hopefully things will be better tomorrow.
