Sleep. More precisely, its absence.?

Sleep. More precisely, its absence. ??? We've been at it for 6.5 months. On IV. He wakes up three times a night. At 9 PM he falls asleep, until 11 PM he sleeps normally, and then the concert starts. He cries, throws tantrums, gets angry, doesn't want to lie down, in his arms, or in a stroller. It's hard to get him to sleep after 1-2 hours. He sleeps soundly, rustling, movement, immediately wakes up. This has been going on for a month now. There are no teeth yet, the gums aren't swollen. Lord, just give me strength ???
