We did a little digging and found baby pics of our One Direction boys! They were seriously the cutest little kids ever too...really.
We need your help figuring out which 1D member is which though...because we totally can't tell them a part.
If you can figure out who's who, let us know which picture is your favorite!
VOTE: Whose grown-up look do you like better, Niall Horan's or Louis Tomlinson's?
