What common mistakes do parents make? Do also describe what the consequences of those mistakes tend to be

For me personally is "letting go"; i am a very sensitive and lack of confidence person due to my upbringing. Hence, I often over protective of my kids. Lucky, my husband is there to point out to me and encourage me to trust my kids. Great to see the growth of confidence and self esteem in them now. I won't say it is a mistake but a learning process for my Husband and myself to learn to understand my children (both strengths and weaknesses) to guide and support them in the manner they understand most.
