Most babies generally hold their heads up relatively steadily at about 3 months of age, but each baby’s development is different and there are individual differences, so the time to hold their heads up also varies. A baby who is 1 month old may raise his head slightly when lying prone, but will soon lower it again. 2-3 months old can slowly raise his head for a longer period of time than before, and can hold it at an angle of about 45 degrees to the bed, and at 3 months old it is more stable. In addition, after birth can be appropriate head lifting training, but pay attention to not too long, time will be more tired newborns, affecting the effectiveness of training, training time is generally in 2-3 minutes or so.
