This week add a change of clothing to each members pack. I know what a pain this is if you have kids and they grow overnight,and it gets expensive. But like other items in your kits, like food, it should be rotated every 6 mths to a year. It is best to have something for warm weather and cold. I have to keep in mind extreme Utah temperatures-you don't want to freeze or overheat.
All I did was go through my kids closets and look for come clothes they don't wear that often or at all. Don't forget socks, and underwear as well. I found an extra pair of shoes for each child at the thrift store for $3 each. I bought 1 size bigger than they are now. My baby was the easiest since she has so many hand me downs from her sister and cousins:) It annoys me that the kids clothes don't match or look that great, but it is an emergency not a fashion show!
For me, I put in a pair of old scrubs---that way I can adjust them if I am pregnant.
This is essential since you may only have time to grab your bags and evacuate. If you are in your pj's and barefoot, you may have a problem.
