You can see in this thread why they use a child. Because any criticism will be met with the defence of "It's disgusting to say that about a child"

The Nazis also used a child to spread their propaganda. That child was also a girl, that girl also wore her hair in pigtails, (or whatever style of tails they're called which Greta wears her hair) just a coincidence, I'm sure.
