My kids fell all the time, off the beds, shopping carts,high chairs, kitchen chairs, bathtubs, swings and on and on. It happens.
But did any of them ever have a fractured skull?
My sister in laws kid has taken several falls from climbing on the kitchen table/chairs. The last time, he went unconscious and was out for several minutes. Now he is "slower" than he otherwise would be....
Some parents just don't watch their kids close enough and although accidents happen, nothing replaces supervision and being attentive, so "bad" falls don't happen.
BTW, nothing against you by my post.
Sorry, but a 7-month old falling from a high chair is NOT normal. I have a 6-month old in the house...he is NEVER unsupervised while on the high chair, nor is he EVER left unsecured. There is a reason the modern high chairs (since I don't remember the one I used as a baby, of course,) have 5-point fall restraint belts.
And, waiting 6 days after a 7-month baby falling, to take him to the ER to see what's wrong?? I would ask if Britney and Kevin are idiots, but that's already been proven repeatedly. They are white trash, and it's been proven, but if they will not take proper care of that child, then someone needs to step in and do the job they are clearly unqualified for.
