Best parenting advice?

Heath • Pregnant with second baby. Daughter is 2. Married for 5 years.
What is the best advice you have been given about parenting?
For me, it was "Don't parent based on what others will think, parent the way you need to". It seems simple but it is a helpful reminder when someone you love thinks you are overreacting or not disciplining enough etc... You are the parent, the baby is entrusted to you-not them.
