My bambino is so young and starting to get forward head tilt.
Should be corrected soon with new computer set up, awareness and this technique of pushing back of head into pillow (to lengthen and strengthen back of neck).
Done with back against wall bent knees strong legs press feet and press back of head into pillow hold for a bit repeat.
If you look at your kids posture don't be surprised to find this issue as many kids now have it (adults too) from looking down at electronics.
Strengthening the rhomboid muscles (muscles next to upper spine between scapularis also known as shoulder blades) will further help.
