Why do people put bridles on baby horses?

To get them used to it and be able to lead them.

Perhaps to start getting them used to it, or in order to lead them with a teather? Though I know nothing about horses.

Easier to lead the foal around and generally become more used to bridle and interaction through the bridle

To show the little shit it's place.

It's a halter, not a bridle. Halters are for leading them, bridles have a bit and are meant for riding.
