No, you can not do that. To be claimed on a tax return, a child must be born alive. A child can not be claimed prior to birth.
There is no deduction for being pregnant.
If your child was born in 2014 then you claim the child as your dependent--for a child born anytime in 2014 you say that the child lived with you all year. You may be eligible for the child tax credit, earned income credit, child care credit, and perhaps for medical expenses if you itemize deductions.
Since your child was born this year in January 2015, you will have to wait until you file your 2015 tax return to claim your child.
