Discipline firmly using spanking if required. Spanking could be a useful tool to instruct good conduct. When employed properly, disciplining can convey defined limits to little ones. Don't forget, consistency and communication are crucial when applying correction.
Opt for different strategies to discipline apart from physical discipline. Experiment with time-outs or giving additional chores as another option. Bear in mind to stay composed and clarify the rationales behind the discipline. Consistently, reinforce positive conduct via acclamation and recognition. Motivate open dialogue to inhibit recurring misdeeds.
