The time the baby looks up
When the baby is 2 to 3 months, it can be lifted 45 degrees above the bed surface when lying prone, or the baby may try to do a small amount of left and right rotation. Most babies are more than 2 months old and can look up for about 30 seconds when lying prone, but it takes more than three months to raise their heads. Some babies with good neck development can be less than three months old, and some babies can only be four months old. There are individual differences in the baby's role.
Baby rises abnormally
It doesn't matter if it develops in the cervical spine. If your baby's muscles are weaker, you may look up later, but it's usually at normal time. However, if the baby can not stand his head after 4 months, it is best to go to the hospital to see if it is caused by a physical defect.
