That's a very slippery slope that I would prefer to avoid altogether. I'd much rather let him find out the truth about Dinosaurs and Christmas from the other kids at school...just like his questions about sex.
I wondered where I could go to get some honest answers about Dinosaurs and Christmas? No really! How can you believe in two mutually exclusive and opposing ideas at the same time?
To be honest

I was hoping to be accompanied by
Stockwell_Day, Canada's Minister of International Trade.

Stock is the only Canadian politician brave enough to admit that he believes in a Flinstonian version of History
in which people and dinosaurs lived side by side.
Like Mr Day, 46% of Canadians have discerned, mostly on their own, that the Flood really-really happened, I mean literally.
More Americans (61%) seem to rely on alternative sources other than evidential discoveries made and reported in Science, Geography, Archeology, Paleontology, Biology, and History Texts, for their information on Global Flooding, and more power to them.
In fact three of the Republican Presidential Candidates, Sam Brownback, Mike Huckabee, and Tom Tancredo, had enough sense left in them, to admit that they do not believe in Evolution.
Damn straight.
I needed answers, and fast.
I have wasted the best years of my Life trying to separate the wheat from the chaff and the bull from the sh*t.
Like many others before me, I may might very well decide to throw caution to the wind, and acquiesce to what appears to be incontrovertible evidence, that Creation Scientists have nailed it.
Don't take my word for it read it for yourself.
Ken Hamm, the mastermind behind ANSWERS IN GENESIS, deflects tough, simple, questions with equally tough, simple, answers.
When did the Dinosaurs live Ken?

"God made everything in six days and Bible scholars will tell you that the Hebrew word for day used in Genesis 1, can only mean an ordinary day in this context."
Fair enough.
"Contrary to what many may think, what we know now as dinosaurs get more mention in the Scriptures than most animals."
Get out?
"The Bible teaches (in Genesis 1:29-30) that the original animals (and the first humans) were commanded to be vegetarian. There were no meat eaters in the original creation."
So Christmas should be a Vegan Celebration?
D'OH!
"Furthermore, there was no death. It was an unblemished world, with Adam and Eve and animals (including dinosaurs) living in perfect harmony, eating only plants!"Shut-UP!?
"There is no proof whatsoever that the world and its fossil layers are millions of years old."
Why doesn't everyone know about this?
And then he dropped the bomb..
"No scientist observed dinosaurs die."
WOW!
"If you remove the evolutionary framework, get rid of the millions of years, and then take the Bible seriously, you will find an explanation that fits the facts and makes perfect sense."
Well you got me there Kenny.
I feel as though a great weight has been taken off of my shoulders.
"Evolutionists declare that no man ever lived alongside dinosaurs. The Bible, however, makes it plain that dinosaurs and people must have lived together.
Perhaps people and animals were killing each other; maybe dinosaurs had started killing other animals and humans."
It's all starting to make sense!
But Ken, I was obviously misled to believe by 99% of Scientists, that the Dinosaurs all disappeared 63ish Million years ago..
HOW?
"They drowned. All of the land creatures outside the Ark died. Many would have been covered with tons of mud as the rampaging water covered the land and the dinosaur fossils which were formed as a result of this Flood, were probably formed about 4,500 years ago, not millions of years ago."
I feel so stupid..it's as plain as the nose on your face.
"It is obvious that evolutionists don’t know what happened and are grasping at straws."
Pfft, you're tellin' me.
"There are some scientists who believe a few dinosaurs may have survived in remote jungles. Dinosaurs can also remind us that God judged the rebellion in Noah’s day by destroying the wicked world with water, resulting in the death of millions of creatures."
Bloody Dinosaurs, those bastards got what they deserved, every last one of them.
"Creationists, of course, would not be surprised if someone found a living dinosaur".
Awesome!
That would be so cool!
Well I hope that this information will help you decide what to tell your children about Christmas. It's never easy to lie to them year after year. Perhaps now you can break the chain. Why not make this Christmas one to remember.
The sooner you let your children in on the worst kept secret in the universe, the sooner they can begin to take advantage of the other children and get ahead in Life.
From all of my incarnations here at Homo Escapeons,
we wish You & Yours, a very-evolutionary..
DINO-MITE! CHRISTMAS
