What is in your diaper bag?

I'm a TAD OCD. I'm not always organized, but when I'm organizing, the obsessiveness shows through pretty bad. However, when there is a situation, I like to think of it as more of a talent than a problem!

So one of the things I'm proud of is my perfect diaper bag. This may not be the perfect diaper bag for you, but for me, it has everything I need. I got a Petunia Pickle Bottom Touring Tote because it has just the right amount of pockets and is just the right size. 

My diaper bag has:

• diapers
• baby wipes
• two disposable changing pads
• my Hugamonkey (of course)
• hand sanitizer
• my coupon organizer
• my wallet
• empty sippy cup (for filling on-the-go)
• keys
• phone
• gum
• pacifier wipes
• two clean pacifiers (in a small tupperware)
• Chapstick
• travel-size Aquaphor
• Band-aids
• Wet Ones
• gas drops
• gum
• Tylenol
• purse hook
• fruit snacks
• travel-size lotion
• pocket knife
• nail file
• fingernail clippers
• travel-size Kleenex
• each child's immunization cards
• infant Tylenol
• Colgate Wisps
• a rotating Star Wars toy (for my 4-year-old's entertainment)

I took a picture so you can see I'm serious! I left my HugaMonkey last time I was out, so it's not pictured, but I promise it fits too! 

What about you? Is there something I left out? What is a necessity when you're on-the-go?
