Positive Reinforcement
Parents often use a reward system when potty training a toddler. M&M candies, stickers, or other small rewards can be used. Each time a child does a desirable behavior – for example, sitting on the potty, having a dry diaper in the morning, or going to the bathroom on the potty – the parent gives the child a reward. The hope is that the child will continue to exhibit the desired behavior because he or she wants to earn the reward, until eventually the behavior becomes a habit.
