There are parents who go along with other parents or relatives when they tell them what to do or how to do it about their children. They go along with them simply so as not to conflict with them, they say yes, but then they do what they think is best in raising their little ones.
This helps you save energy and creativity for your children, without having to tolerate other people's comments. The Japanese don't waste time trying to figure out why the problem occurred or who to blame, they focus on the solution… great lesson for everyone! So, Devote your energy to what you can change and where you can make a difference, not where you can't.
One of the most difficult things for parents of children with and without special needs is dealing with criticism from the people they value and love the most. Lparents can deal with feelings of guilt, Some think that they are not good parents and that because of those their child is how he is, but nothing of that.
What is important is that the criticisms of others do not take it as a personal attack, if they serve you to reflect it is fine, but if they are not constructive and are more destructive than anything else, then it is better that you do not listen to them. Your son is neither good nor bad, he is just a child that you are educating. Get closer to the people who show you their affection and whose comments help you to be a better person and a better father or mother. Do not identify with the bad words, And if you ever feel disoriented in raising your children, then ask a professional for help to guide you with educational guidelines to apply at home, both for parents and children.
