He likes cats so we could go that route with one of the various cat/tiger/lion costumes. He doesn't really know his animal noises yet (should he?) so there is no animal he could replicate well yet so there isn't any great ideas there.
And then there are some of the geeky costumes. Admittedly these are mostly to satisfy mom's geek tendencies and yet they could be fun. But I can't decide. So what do you think blogland? Do you like any of these for baby goat's Halloween costume?
The crayon: gender neutral and also available in blue, red or yellow
An Ewok - cuteness factor high, but would he keep the headpiece on?
Ah the Muppets - Kermit would be great - and could e find him a little banjo too?
Captain Kirk - easy costume and wonderfully geeky. There is a Mr. Spock too but baby goat's personality may be more of a Kirk (aka Ladies man)
Mario - I love the mustache!
Obi Wan Kenobi - this is a great costume too but we'd need a light saber I think
On the flip side you could go with the evil Jedi master!
Finally, moving away from Star Wars, Charlie Brown is geeky and there is a MN heritage thing here too. But couldn't I just make this? Maybe?
