I think family might be the most important effect to the person who is a gay or lesbian or not.
No, the question was about the outcome of a situation with same-sex parents.
parents can notice a different behavior even when a kid is quite small.
This is true! A lot of research supports your view. But still, the essay is about same-sex parents.
Anyway, Janet, tell me what you think will happen if a child has parents that are the same sex (i.e. two homosexual men raising a child). Write one sentence about what you think the "effect" will be.
That is your thesis statement, and it should probably be put at the end of the first paragraph.
