I agree accidents happen .. I've had 3 children of my own who have scared the daylights out of me at times
but they waited six days before having him checked out?
Having been in emergency rooms with small children, a lot of times the advice is to "just watch them. If they seem overly sleepy, or start throwing up, then bring them back."
For some reason, it always seemed at my house, these freak accidents happened at Christmas, or some other holiday or get together.
