Are Abraham Hicks' teachings really real? I have my doubts.

EDIT: @StoriesAtSunset ANSWERED ME GUYS. Relax, I believe in Abraham teachings, that was just a thought, thank you StoriesAtSunset, that's make perfect sense!

I'm not a hater; in fact, I’ve probably listened Abraham more than most people reading this. I’ve practiced, bought books, and attended seminars. And I manifested money, relationships, and cures. But I have two questions.

1. If I tell my 5-year-old son, “This is a lottery ticket. If you pick 5 numbers, you’ll win a lot of money, meaning you’ll get toys and fun things to eat!” he’ll believe me because kids believe in things completely. They even believe in Santa Claus. Will he manifest the lottery? I guess not.

So how does this work? Abraham Hicks says to believe, but I remember, as a kid, believing for a WHOLE YEAR that I would get a toy—and I didn’t. So what happened there?
