We have three adults (me and DH plus DS1) and one toddler. The toddler generates more washing than us three put together!

I've been doing a load each night and hanging it out in the morning before I go to work. On the weekends though, I do more - towels, teatowels, sheets etc.

I've given up sorting colours unless I have delicates to wash (some of my work tops and cardies) then I'll pop them to one side and do them all together on the weekend. TBH I think that things are more colourfast these days and don't tend to run like they used to....either that or I've gotten used to "grey".
