S.T.
my boys both had short 'hawks when they were little (well, my older still has one occasionally now, only the tall lacquered kind) and they were adorable and very easy. we went very very short on the sides, almost to the skin, and short on the 'hawk part, not much more than an inch. as long as it's relatively short it will stand up with basically no upkeep at all. as they start to grow out they may need a touch of mousse or hairspray, but nothing labor-intensive. i'm with you, i have no patience for hair primping. but my boys' mohawks were incredibly easy.
i think it will be absolutely enchanting on a little girl.
