Based on the described situation, the baby’s refusal to drink milk properly and crying when put down may be due to poor digestion or a disrupted biological clock. It is recommended to pay attention to dietary adjustments and avoid overfeeding. Consider slightly reducing the amount of milk to help restore gastrointestinal function. Gradually cultivate the habit of the baby sleeping in bed. Wait until the baby is more asleep before placing them on the bed. Initially, they might wake up as soon as they are placed down, but with some training, the baby will prefer to sleep in bed. Crying is not harmful; a few cries are fine.
