Keep in mind that the "housing" cost includes either moving to a bigger property, or simply assigning part of your current mortgage costs to your child. If your house is sufficiently large, there won't be any much additional cost here beyond an increase in utility usage.
Similarly, transportation downloads a lot of the cost of a vehicle to your child. Maybe you do need a bigger car, in which case that makes sense. But maybe your car is fine, so the only added expense is gas and maintenance for the extra mileage for children's activities.
No such thing.
