Umm...am I missing something?

I found this blog and as I was reading through it I really confused. It is written by a self described Calvinist who is attempting to answer a very poorly written post attacking Calvinism on Facebook.

I am hoping that someone can help me with this post. In case you did not know, I am not a Calvinist. I have done a lot of reading and I think I have a pretty good understanding of the tenets of Calvinism. At least I thought so until I read this article. Please read this article and then take a look at my questions below. Please read the article first so that you are not prejudiced in any way. If you are a Calvinist please forgive the attitude in the original post to which this author is responding.
The Blog

So, my question:

• Is this author saying that his children are elect because He is elect? "The promise of the covenant is to Abraham and his children." This would go against unconditional election would it not?

I do not see how this person can say some of the  things he says. "From these activities and others such as regular attendance at church, you heard over and over again the great promise of salvation. And this was most vividly displayed in your baptism, that signified, among other things, you belonged to God." Is this a part of child baptism beliefs? Does this place them into the elect? Help!

The author also fails to deal with the poorly worded diatribe's complaint about Calvinism. Pointedly, that Elect parents have no way of knowing whether their children are elect. This Non Calvinist and many others have a good deal of trouble understanding how a God who gives us instructions on how to raise our children Eph. 6:4, Deut. 6:6&7, etc. when He knows that the child is or isn't elect.

I personally cannot see a God who deals thus with His children as a God worthy of love or worship. Fear maybe, Love No. And I mean Freddy Kruger fear, not awe and respect fear.

Calvinists do not deal with this issue well. (John Piper did say he was aware that one or more of his children might not have been one of the elect.)

Here is one response I have received many times:
Me: According to Calvinist teaching at least one of my children could be one of the non-elect.
Calvinist: True
Me: I can't accept that. If, according to what I see in the Bible, My son refuses to repent and receive the gift of salvation, my son is in danger of hellfire. But according to Calvinism, my son (if not one of the elect) has no chance of salvation.
Calvinist: (this response I don't understand but i have received it many times) Can you through prayer and teaching save your son?
Me:HUH?

I once heard a Calvinist proponent put it this way. It is true that one of your children is un-elect but you can have the utter confidence that the other if elect is forever safe from Hell.
What possible comfort is this?
