I so relate to your post! Our parents are just humans themselves and aren't perfect although growing up to about the age of 10 or 11, we think they are. Best thing to do is be a great role model to them. Working on yourself and continuing to improve and learn is so important as it shows your child that life is an ongoing process of growing.
I remember when I was around 10 and I realized that my mum makes mistakes and she doesn't know everything! I was mind-blown lol! I think the most important thing is to be close and genuine with your kids, talk to them as much as possible, be honest and apologise when you're wrong. Be their friend! Thank you for taking the time to read my post.
