Lifes little emergencies - do you need an "ER Kit"

Rachel (5YO) closed Noah's (2YO) wrist in the van door this morning as we were leaving the school. So I've spent the whole day at the hospital just to make sure nothing was broken.
I've been meaning to make up another 'kit' called an "ER Bag" - useless to most adults, anyone with kids will appreciate the idea. We keep an emergency kit in the car but it only has... you know... *emergency* stuff in it. I also keep a random book in the car at all times - puzzle book, magazine, something in case I'm stuck in the car waiting. The ER Kit would complement your car kit without taking up as much space as a BOB - which would be overkill in this situation.

The idea of the ER bag is to have a small bag or shoebox size tote near the front door or even in the car if there's room. That box would contain a few snacks, small toys, coloring books, crayons, etc. The thought behind it is that the emergency kit in the car doesn't need to be cluttered with toys but I want to have *something* so I don't need to run around the house collecting things to entertain the other children; and I don't want to dump money into the vending machines at the hospital when someone gets hungry after sitting in the ER for 2 hours. I already keep diapers, water, change, first aid, etc. in the car kit; so this would just be something small to hold the remaining items. If you car kit has the room you could feasibly just add these items to that container.

So, think back to the last time you had to 'grab and go' with your kids. What were you wishing you had brought with you? Here's my list:

• drinks - juice boxes, kool aid koolers, water bottles... ANYTHING that doesn't cost $1.50 per bottle!
• Snacks - Those little snack packs they sell in the vending machine for $1 or more can be had 9 for $3-5 at the grocery store. Even if they go unused for 6-12 months they can be used as a 'safety reward' if the kids can go 6-12 months without a trip to the ER (Well worth the investment!!)
• activities - coloring books/crayons, travel games, matchbox cars, little people, deck of cards

A few other suggestions/ideas - an MP3 player or other portable player, a lightweight blanket (certain areas of the hospital are cold), maybe a travel pillow, a book

None of these things are necessary, but they will all make a difficult trip a bit more comfortable and less frustrating. I wish I had one in my car this morning. It was also a good reminder to give my preps a semi-annual complete overhaul
