Babies don't need pillows until they are three months old.

Many old people are used to giving their babies hard pillows after they are born, which is wrong. However, some young people think that they can't sleep on hard pillows, so they will buy children's pillows and shaping pillows in advance, which is also good for their babies, but it is also wrong to do so. Please remember that babies should not use any pillows until they are 3 months old. Because it may cause problems to the baby's spine and head development.
