Babies are cute when they are young and going through different stages of growth. But when they get older, you don't expect them to act like babies! It is normal to grow and mature. Something is wrong if this normal development doesn't happen. We need to be growing as Christians into maturity, and moving on to other things (Hebrews 6:3). Growth is our responsibility, and it always involves change. If we don't change, we won't grow. We need to be teachable. If we are satisfied with where we are, we won't want to move on and we will stagnate. We always need to learn. The Holy Spirit is always ready to teach us, and open up new ground to us.
