If we're asking can children be consciously gay, then no, I don't believe they can. I don't believe they can consciously be straight either.
Even though it's predetermined from birth that some children will be grow up to be gay, and others straight, sexual orientation remains very much dormant throughout childhood. It's not until puberty that anyone can experience a true sexual attraction, and then use that to accurately identify what their orientation is.
Trying to peg a sexual orientation on children is more a reflection of the adults around them than the children themselves.
