I sorta ignored the 5th one because I feel like it's too obviously the answer, with it in there it basically almost becomes a "if you could custom order a pacifer what would it look like" thread which sounds like a completely different thread.
So I eliminated that option and went with the others. For simplicity sake I found the best way to internalize it was; I'm going to be given one of them free which do I choose?
I ended up choosing Minnie! 2 really wasn't an option for me, I really don't like to feel "possessed" and the whole "I'm daddy's girl!" thing is yucky to me. After that, I'm not much of an animal person so generic pictures of animals really isn't my thing. Ended up choosing the character among them. Minne is pretty awesome and she's got good fashion sense usually.
I'm fairly male but my little is kind of gender ambiguous (I think most kids under the age of about 2 don't really have an idea that they're any specific gender and that's kind of where my little is). I don't think these pacis would feel wrong for my gender.
