And, I have honestly replied that I don't think it is possible. A toddler in a mustache is just too funny so the best I can do this year is to try to match it.
Initially I was thinking he could be Woody from Toy Story since he talks about Woody nonstop. But, he was a cowboy when he was one.
And now he is a big 3 year old that won't wear hats...except this cool fireman's hat that he got from a safety talk at school. So...fireman it is.
The jacket should be sturdy and warm considering he has 4 or 5 places to wear it in the next week.
Perhaps he'll run across a real fireman that can teach him why fire hoses don't go in the mouth.
