In order to move forward, you have to let go a little bit.
This is a scary life lesson you are learning as you try to crawl. You get up on your hands and knees with no difficulties. You rock back and forth with great enthusiasm. You even inch your knees forward or slide back on your knees pushing off with your hands. What is frustrating you so much is that in order to move yourself forward, you will have to pick up one of your hands…and you aren’t comfortable doing that yet. This means that Mommy and Daddy have to worry about you rolling over off of the bed or changing table, or scooching yourself into a corner of your crib backwards and not being able to get out. Mommy and Daddy have tried to show you how but have concluded that this is just one lesson, like many, that you’ll have to learn for yourself.
