Are there any requirements for's pillows?

Patient's question:

I want to ask what kind of pillow is suitable for a 4-month-old baby? Can they sleep on a buckwheat hull pillow? Online

Doctor's answer:

Children sleeping on hard pillows is not good, as it affects brain development. It's better to sleep on softer ones. However, they shouldn't be too high—1~2cm is ideal for babies around six months old; the pillow length should be the same width as the baby's shoulders.
Child health issues have always troubled parents. When treating such conditions, it's advisable to consider general treatment. Only by using professional methods can parents help children recover quickly from illnesses without affecting their growth and development. Therefore, it's crucial for parents to seek prompt treatment for their children if they fall ill.
