My daughter is 2 months old. During the first month her sleep cycle was good, she slept well during the night, only woke up for feeding. Past 2 weeks her cycle has changed, she sleeps well during the day between 12-4, 12-5, but during night she doesn’t sleep. Most of the times she is awake during the night and sleeps around 5AM-7AM. During the night we need to calm her, pick her up, feed her etc due to which our sleep is disturbed. We make sure lights are dim, we try to make her sleep in the lap. She takes a nap of 30 mins or so and wake up again. What can be done to fix the sleep cycle ?
