Hello moms. We have such a story. The schedule went haywire, we don't understand why, all bedtime rituals are followed, walks, bathing, pajamas and sleep. But now he sleeps for 40 minutes and wakes up at 12 pm and doesn't sleep until 1 am or 1:30 am, we go to bed at 10 pm. There are 4 daytime naps, we don't oversleep. Then we get up at 5 am and walk around until 7 am, chatting. ? How do you level the child's schedule.? And one more question, I will ask immediately in one post, the child became very very crying,
