I've heard a lot of experience of people get caught wearing diapers by their parents, including my self, but actually it's not so complicated if we can control our emotions and thought when it happened,
*Take control of your fear
Do not let fear haunting and control yourself, make sure you stay calm, because one of the biggest problems that often occurs because we always fear what will happen because our secret get caught, I suggest to remain calm yourself, Do do not fear to much so you can prepare to explain your intentions to your parents. Also make sure that your parents are not suspicious of you behave, so they will not feel to weird when they find you are wearing diapers.
Note: when you're afraid, you talk will get stutter and it will make you difficult to speak clearly, of course you parent will feel strange to see you, make sure you don't fear to be able speak and explain clearly.
*Tell a good explanation and reasonable
Maybe when get caught, parents will ask like this: "Diapers, what the meaning about this!?" according to first tip to keep calm and say what you mean and feels clearly to parents, do not just say "I JUST LOVE IT" or "I JUST WANT TO BECOME BABY AGAIN" it didn't helpful, parents wanted a clear explanations and reasonable, so that they can take appropriate action for their children later life. and certainly they will understand what do you mean.
You: Oh mom, forgive me if I don't talk about this for you before, but all I want to say is this is my actually life, maybe you'll find me weird, but I cannot live without all of this, this weirdness make me can live, I hope you can understand me, mother.
Note: if you still haven't get caught, it's better if you take another look from internet, a real sense of ABDLism or Infantilism knowledge, to provide your explanation to your parents.
*Control you emotions
Do not get angry or cry if you get caught, why? Because if you're angry, it means you against your parents, it will make your parents feel opposed, and you know the consequences. And also do not cry, i've heard people crying because their get caught wearing diapers, it will not help, because parents don't want pity, they need an explanation.
Note: Don't need too much emotion when explain or say something, if you want to say or explain, say it seriously and without any sense of angry or sad.
*Give an explanation with positive examples to them
Provide an explanation with positive examples of ABDLism to your life, because parents would not let their children live with negatively things, they need something positive to they children. So they can understand and recognize what are you expressing. The examples here for they can better known and understand your opinion was good.
*Discussed together for solutions of your ABDLism.You: Mom, with this my life is much better than before, I was also getting more excited about living when in this life, not because I'm weird, but I need a comfort things in doing my life.
If your parents already accept you but their still not sure, it's better if you discuss it with your parents, the purpose of your discussion with you parents is to find a way out or solutions about how it should be. Discuss the solutions you have and given by your parents, so that your parents can find the best solutions for you to live in ABDLism.
You: Mom, if you're still not sure, how if we discuss together about what the best for me, I'm sure you still cannot believe me, but you must believe me don't be afraid, it will not ruin my life, I still can become your great child and can you give the best suggestion to me?, I will appreciate it for the best to me and you mom.
*Say thank you and love them if they accept your ABDLism side
Thanking and love your parents, if they accept your ABDLism side and whatever happens still love your parents. Because they are the number one for us. Whatever you parents must do is the best for you, because parents had the instinct to protect and provide to their children.
Remember that ABDLism will not ruin our life if you can control it by your self.You: Thank you mom, I know that you get little annoying in my life like this, but I believe you can understand me, every people has their own way in their life and I believe this is the best for me,
thank you for can accept me mom, I will always love you as my best parent in my life.
