Wheel Pose - Tips for a better alignement

It took me some time to adopt a good wheel pose, which is a bit addictive! Try this pose, after a proper warm up for your spine, shoulders and core.
How kids can do it so easily?

Begin on your back, knees bent and feet hip-distance apart. Place the hands by the ears with the fingers pointing toward the shoulders, and hug the elbows in rather than letting them splay out (think Chaturanga arms). Find a little arch in the low back, let the glutes get heavy, then lengthen the tailbone. Carefully lift yourself to the top of the head. Take a moment here, and move the arm bones back and forth to find the mobility in the shoulders. Draw the shoulder blades in toward the spine and gather the arm bones snugly into their sockets. Check in with the legs to make sure the glutes are still unclenched and that the knees are aren’t drifting outward. Finally, press evenly into the hands and feet and lift up to Urdhva Dhanurasana. Gently pump the chest forward, checking in with both shoulders and spine to make sure you don’t push past a manageable range of motion.

If there’s discomfort in the wrists, try placing a rolled up blanket under the heels of the hands: decreasing the extension demands in the wrists will allow the shoulders and chest to open more freely.

To come out, lower the top of the head down first, followed by the hips, maintaining a slight arch in the lumbar as you release all the way down. Pause here, before gently sweeping the knees from side to side to work out tension in the spine. Take your time carefully hugging the knees into the chest to counterpose.
