One of the common mistakes that many parents make is that they always assume they must always appear perfect to their child , they keep thinking that as parents that they are not supposed to have their own flaws or that they are not supposed to make their kids know about their flaws..
Nothing is wrong if your kids know that you are not perfect ,let them know that you have your flaws too as a mother or as a father ,let them know that because you are a parent do not mean that you are always going to be perfect, let them know that is not bad if they make mistakes, , what matters most is that they should learn from their mistakes..
Do not allow yourself to become so inconsiderate when dealing with your kids just because you expect them to always be perfect or that they should always do things perfectly..
If possible let your kids know that as humans they cannot always be perfect and so they should not feel depressed whenever they make mistakes..
