This year we were a Nuclear Family for Halloween, with our 4-month-old daughter Corvidae dressed up as a 3-armed happy mutant.

While we wanted to be subtle, this was almost too subtle - she wore the costume all day, and hardly anyone noticed!  But when they finally detected a problem, the responses were excellent.

This instructable documents the creation and care of a 3-armed baby.  If you make your own, please post pictures!

Step 1: Find radiation sources

As with many superheroes, Corvidae's mutation is the result of irradiation.  in this case, both of her parents take serious rads on a regular basis - Eric as a Beam Engineer at North Central Positronics*, and I as head of the Experimental Radiology department at Mid-World University*.

Caution:
radiation-induced mutant powers are highly idiosyncratic.  We cannot guarantee your child will be born with super strength or telekinesis, or that any extra limbs will be fully functional and/or not evil.

Since we had to leave our real badges at work (pesky government regulations!) Eric quickly cut duplicates on the Epilog laser cutter.


*Hat tip to Stephen King's Dark Tower.

Step 2: Find duplicate outfits

To clothe your adorable 3-armed mutant, you'll need duplicate outfits, as few baby clothes are sold with an extra sleeve.  Choose highly-patterned clothing for best results.


Step 3: Find suitably-sized doll

A similarly-sized doll can be useful in sizing the costume for your 3-armed baby.  We'll use one of its arms to mock up the outfit, though of course we'll substitute Corvidae's real third arm when she wears the outfit.

This doll has realistic plastic hands, and a cloth body - perfect for our purposes.  Choose the hand with the most realistic positioning.

We loved this idea and made our daughter a 3 armed baby for Haloween 2011. It's a big hit! Thanks for the idea.

Amazing! Too bad I saw just now, three days after Halloween. My baby would have such a great mutant! I wander if you could be a mutant on Purim?

I liked the fact that nobody realy picked up on it. That's what I call a costume. Cute kid
This is fantastically, beautifully, wonderfully subtle. I love it!

It doesn't hurt that the baby is just a little bit cute.

That's gorgeous.
Perhaps next year you could do a beeblebaby. http://www.zz9.org/merchandise/beeblebears.html
Hi Canida, this is such a clever idea and her smile is utterly adorable! I just had to include it in "10 Halloween costumes sure to get a smile" (http://www.homemakers.com/blog/brightside/2010/10/29/10-halloween-costumes-sure-to-get-a-smile/). I've emailed you about this and hope you don't mind us linking to you. Janet
That is an awesome costume - what a great idea! Also, your baby is incredibly adorable and lucky to have such creative parents.

No mutant babies were harmed in the construction of this Halloween costume. Can't say the same about dolls, but at least this "Chucky" won't be doing anything left handed... :-)

Great job by the way.

Excellent!

The rest of Australia reckon us Tasmanians have got two heads... this would show them!

Excellent!!! When he gets older, this child will probably fully appreciate the humor behind this wonderful gag. This is one of the funniest things I've ever seen-- Hope you'll keep evolving. I love humor.

for people in toronto go to active surplus there known for there baby parts
The limbs have moved from a shelf to a bucket at the back. :-)

The bucket of arms must give a few people a start as they walk by.
Cute!

As far as I'm concerned, awesome Halloween costumes the #1 reason for having kids!

Well, awesome Halloween costumes that are recorded on the Internets for blackmail purposes in adolescence. ;D
 Hands down the greatest baby costume I have ever seen!

Just a suggestion for IF you wanted the other arm to move on it's own-
You could connect it to the upper one in a couple places with a bit of fishing twine. 
Awesome by the way :)
 would fishing twine not be a bit thin and possibly lethal?
What do you mean lethal!?
Maybe I didn't explain it very well.  I suggested that someone could tie a bit (maybe an inch or two) or clear plastic string from lower arm's sleeve to the upper arm's sleeve so that when the real arm moves, the other will follow, because it's attached to the real one.  Thought it could be kind of cool, instead of just having the fake arm hang there.
...I dont really understand how that could be precieved as lethal.  If I am incorrect, please explain it to me.
 Sorry - I misinterpreted your comment. I thought you meant tying fishing twine round the REAL arm and thread that through the clothes to the fake arm, possibly cutting off the blood flow. Sorry. Silly Me! :P

 I see l'm a little late, but this is a great costume! I love that it's so subtle and kinda disturbing. It's fun to play with people's heads, even if you ended up doing it inadvertently!  I had a similar Halloween: When I was in 5th grade I dressed up in street clothes with a ground-off six-penny nail glued to my forehead in a bit of bloody wax scar material. Far more people invited me into their houses for first aid than offered me treats! It was a really strange and fun experience (that led me to become a makeup artist for a while!) Good job! 

My son is now old enough that all he wants are commercially popular costumes - but at least I get to make them. Enjoy this time!
