Paycheck after a baby!

I have a question and, since I've got different answers, I decided to ask here and see if someone knows.
Does the base pay or BAH increases after adding a baby as a dependent? If yes, how much approximately?
Some people said to us it does and some people said it doesn't.
It's our first baby and we are start to see how our budget will change after our little one arrives. 
Thank you in advance :)
