We have three girls who’s are 8,3, and newborn. I have custody of the 8 and 3 year old for 156 nights a year. I may agree for my wife to have full custody of the infant for one year (breast feeding and bonding). When I use the ROSEN CS calculator, it doesn’t seem to handle this correctly. My understanding is Worksheet A is for sole custody, Worksheet B is for shared custody and Worksheet C is for split custody. My wonderful situation does not seem to fall into any of these categories. The online calculator comes up with a basic child support obligation that does not match the tables (even when multiplied by 1.5). I dont understand this since the basic obligation is either multiplied by 1.0 or 1.5. right? If I use two children it works perfectly, when I put in three and enter the nights and move to the “three children column” I dont understand where the new “child support obligation” comes from.
I’ve read all three worksheet I thought Worksheet C would now be used since she would have full custody of the infant for a year. However, there are no provisions in Worksheet C to account for the shared custody.
I i just average the number of nights for all three kids, it puts me back into worksheet cause the average number of nights is now 105.
My question are:

Can the Rosen Law Firm calculator handle this case correctly and if so, how does it do it? It seems to go to Worksheet B but then uses a Child Support Obligation that I cant find in the table (even when multiplied by 1 or 1.5).

What worksheet should I use in this situation?
Thank You
