In this situation, are you warned of a designated pedestrian crossing?

Why?

The A-17 “Children” sign on the right warns of a place frequently used by children or a location nearby. This sign does not itself indicate a designated pedestrian crossing. The A-16 sign warns of a pedestrian crossing ahead.
