What Ever Happend To Baby Trever?

The very first episode of Desperate Housewives, Edie refers to Mrs. McCluskey watching her son because Edie herself would be "entertaining" a man friend. Later in the episode, Edie's house burned down. The entire neighborhood stood outside behind the yellow caution tape surrounding the ash that was once a home. One of the concerned neighbors were Mrs. McCluskey, without a small boy who could have presumably been Edie's son.

After that episode, viewers did not see or hear about this kid. Until, two seasons later, eleven-year-old Trever came into the picture. He was the son of Edie's that she used to lure Carlos into liking her. (No, that's not a bad reason to have a child at all.) Supposedly Trevor lives with his dad, but I find it flawed that a main character has a son, whom, for two years she neglected to show us.
