Movie about alien conspiracy

For the life of me I can't remember what this movie was called or a lot of details about it. I remember watching it 7 - 8 years ago and for some reason it stuck with me. I remember very clearly at the end of the movie, a couple is given a choice to "save" their son, that's in the next room and had 2 of his senses(sight and hearing) "disabled" by some guy who's not human, the husband has to shoot his wife in order for their son not to be deaf and blind for the rest of his life. I also remember a scene where the same kid is being baby-sitted by a young woman, he's doing homework on the kitchen table and on TV there's some news about some rocket/satellite that's in orbit, I think the kid's father is some astronaut or works for NASA or something, the kid is very smart, he starts telling technical details about space but then the atmosphere becomes tense as the babysitter notices somebody that's not human, menacingly walking outside their house.
