F.H.
Hubby does all the laundry and so he does them about every 3-4 weeks. Same for the kids, they are older and don't have accidents nor do they eat or drink in their rooms. That "fresh washed" feel/smell wears off after the first night in them! Just my opinion but with 5 of us in the house if we added everyones sheets to the weekly laundry it would take forever and I don't think there is a need for it.
