Some work places will let the father have maternity leave if their wives are close to their due date or have given birth. You can speak to your work to see if they offer this. You could also use personal time or vacation time.
Check with your employer to find out what their paternity leave policy is. 2 week is typical but it depends on your state/country laws. You may also be able to work with your manager to get flexible work hours or work from home so that you can be there to bond with the baby and help your wife. Congratulations!
