It is impossible to know your exact tax situation based upon the limited information you can give in a public forum. However, there are a few things we know for certain:
1. An additional child means an additional child tax credit.
2. Lack of withholding means a smaller refund, or you may end up owing.
Unless your income is relatively low, it is unlikely that the additional credit will be sufficient to prevent you from owing. To be safe, discuss the specific details with your human resources department, and if necessary, make an adjustment by filing a new form W-4.
