How are toddlers like professional soccer players?

You can tell them apart usually, but it's trickier when they're running away from you.

"Norwich City's identical twins Josh and Jacob Murphy will wear different colour boots to help boss Chris Hughton distinguish between the two."

"It's not so much in close proximity, because there is a difference between the two and they have different playing styles so I can tell them apart."

I like that "playing style" is a differentiating factor. The ways I tell apart our boys include things like gait, or what they're saying, more often than anything like "rounder face."
