One thing to consider if you have small children is how to transport them quickly if there is an emergency. One suggestion is a sling, ergo, or other baby wearing item. I carry a sling with me at all times even though my 2 year old is a bit big for it, I figure if there's a situation where we have to get away fast (running, walking, whatever) I can throw him in the sling and move faster. On top of that if we are ever in a situation where we have to walk long distance he would be far better off in a sling
