It can be hard to let children take risks. As parents we want to protect them, not see them get hurt. But we have to trust them and give them the opportunities to try, fail, get back up and try again if need be.
Let your inner Elsa fly and start singing "Let it go!" Let go of perfection, and be you. Show your children how to accept yourself exactly as you are and offer them the gift of a lifetime. Your relationship will do so much better because of it. Relieve yourself of the expectation of being a perfect parent.
