You can practice holding your head up at about one month of birth, and the practice should be gradual.
From birth to one month, if you can help your child to practice, then by 2 months your child will be able to hold his head up at 45 degrees or even higher. It is best to practice for less than 30 seconds initially and then gradually increase the length of time, practicing 3 times a day, so that on the one hand the child’s head is raised, and on the other hand the strength of the child’s neck and back muscles is also exercised.
You need to pick the time when your child is in good condition, don’t force your child to practice, and don’t practice when your child is crying, hungry, or uncomfortable. Parents can keep track of their child’s daily progress, and should be present when practicing to avoid risks such as choking.
If the child is still unable to hold his head up more steadily after three or four months, he needs to be seen by a pediatrician to evaluate his neurological development.
