I think its 'as much about the parents' for a toddler, as any other haircut, really.
Did your (1-2yr) toddler tell you to cut her bangs short or keep her hair curly? Etc.
Up until kids pick their own clothes (and some tots have preferences) we're choosing what we want to put on our children.
I wanted to give DS a 'conservative' mohawk, once he was of walking age - but couldn't cut his curls.
I recently cut his curls, due to the heat, and he's a spitting image of Dorothy Hamil. Also, his heads too round for a mohawk.
But, to you moms with boys (or girls
) with mohawks, rock on.
Edit: And, if my child ever asked for any haircut - he's more than welcome to have it. Even if he wanted to buzz it short and put a nike symbol in the back... I'd probably die laughing, but hey - its his body.
