Hello everyone! My son is turning 9 months old in a couple of days, but he can't fall asleep deeply at night, like shallow sleep. He wakes up every little noise and even without noise. He sucks on his mom every 1.5-2 hours. We put him to bed at 8:00 PM +/- 30 minutes, we used to sleep for 3 daytime naps, thinking that maybe the third nap is unnecessary, and without it he would sleep better - we removed the third one, and increased wakefulness time. But he still sleeps shallowly. Even while sleeping, he constantly changes head position, makes attempts to turn over - he can't and cries. Two days
