I am not a dude, or indeed a little man. I may well be cuter than my daddy, or better looking than my daddy, but I do not judge it seemly to declare this publicly. My younger sibling, when he or she arrives, is unlikely to refer to me as his or her "big bro".
My behaviour, within the limits of the capabilities of a two year old, is reasonable if not on occasion exemplary. Therefore I would suggest that slogans which draw attention to it's less pleasing aspects, viz "little but loud", "here comes trouble", "cheeky monkey", "little monster", et cetera, are not appropriate.
I am not in the army, I am not a surfer, a trucker, or a rapper. And I am far too young to have heard of the Rolling Stones, the Beatles, or Guns n Roses, whatever they are.
Like most human beings, I don't suit nasty, dreary, washed out colours such as: faded navy, dung brown, sun bleached green or barely-burgundy. Ditto burnt orange and sludgy beige. I know that the idea of using bright, gorgeous colours and attractive, inventive patterns similar to those used by your colleagues in the girlswear department fills you with worry, but I promise that most mums and dads and other purchasers of children's clothes don't share these anxieties.
And that is all.
Yours,
Monkeytoddler
