If I understand you correctly and I'd let somebody else chime in before you take what I say by the book. At least this is also the way it works in Louisiana.
If you claim yourself or single one of them takes out the most per pay check which means you get more at the end of the year while the other takes out a bit less.
When you start claiming kids they take out less and less and I think at like 2 or 3 you get tax exempt for maybe federal? This is to where they don't take anything out of your paycheck and you still get money back at the end of the year.
Again, please let somebody else chime in for sure and remember that we're in different states. Hope this helps.
