Also when you enter the newborn make sure you read the screens carefully so you properly enter all year for how long did the child live with you. The program tells you to enter the whole year so do what it tells you to do.

So unless the child is a trust fund baby who owns the home you live in the answer will be no. Failure to answer these two items correctly will give you a very unhappy result.
