Is it normal for my 19 month old to still be waking so frequently at night?

The waking itself wouldn’t concern me as much as his inability to put himself back to sleep. Last night he was put to bed at 8:30pm. Awake at 10:30, crying. Needed me to soothe him back to sleep. Awake again at 2:00am, needed me once again. Awake again at 4:30am, needed me. Awake at 6:00am, needed me. Slept until 7:30am. If I leave him to cry he will scream and get so worked up that he throws up and then will not fall back to sleep. His room his cool, he’s in comfortable clothes, he has a fan/white noise. He has access to water. Bedtime routine has been the exact same since birth. I’m not sure what else I can do.
