There are strict laws governing child actors, just like anyone under 18 has laws about working.

There are restrictions on how many hours a day they can work, for example, and schoolwork can't be infringed upon.

However, it's my understanding that Once's filming schedule generally goes very well, so I doubt it's "difficult" for Jared to film.
