I then started to look at other things that may also need to be changed but may slip under the radar. Pillows are another thing that can go unnoticed, this is something that definitely needs regular attention. Even though you can wash them it is still a good idea to purchase new ones at intervals. I recently noticed that a new pillow I bought had a use by date on it. This is a great reminder.
The toothbrush is also another one, I know we are told every 3 months is good but if we are honest how often do we use them for far longer then 3 months. Its not because we don't want to, it is just something that again can go under our radar.
Then there are all the things that we us that start to wear out that also need to be replaced. These things will pop up from time to time letting us know that they need to go.
