My son who will be 1 next week has been waking up the same time every night (12:30) for the past week screaming hysterically and arches his back and pushes away from me when I try to calm him down. What do you think is going on?! It can take anywhere from 10 minutes to 20 minutes to calm him down from the hysterical crying but he will still cry off and on for another 20 minutes. My husband and I are exhausted. We have his Dr appointment in a week and I plan on asking her if it continues
