Will AD Army Allowances change with newborn children?

I am having twins in August/September, well my wife, and we are wondering if any allowances will change with +2 dependents being listed under me as a sponsor. I get BAH/BAS, but not sure if any of them will change with the new additions on the way. I'm sure BAH won't, but not sure about BAS or if another allowance of any sort comes into play with children.
