When daily routines get out of whack, Dr. Grodberg recommends parents check in on their child's basic needs. They may just be hungry, tired, or over- or under-stimulated. All of these things directly affect a child's frustration tolerance. As children get older, you may expect them to be able to communicate verbally when one of these needs is not being met, however, it isn't always that clear. Keep these basic needs as a checklist in your mind anytime you think to yourself, "Where is this behaviour coming from?"
