I've gone weeks, maybe even over a month, without washing my children's bedding.
Geez. Give me a break. There is just so much to wash that sometimes I completely forget about their bedding. Alternately, there was a two to three month period where I washed their bedding in hot water every Saturday because I read that was a good strategy against...oh, I can't remember now...something about the flu or the common cold. Geez, there's just so much to remember about taking care of kids that sometimes I completely forget what kind of perfect mother stuff I am supposed to be doing on a daily (weekly, monthly...) basis.
