What is the standard weight for a three-month-old baby?

At present, the most important thing in a family is children. It is no exaggeration to say that a baby is the life of its parents. When the baby reaches three months old, the family needs to know more about various developmental indicators, and we hope that parents will pay attention to them so that they can better raise and care for their children. Next, I will introduce to you the standard weight of a three-month-old baby.

At 3 months old, the baby's posterior fontanelle has almost closed, indicating that the cartilage has hardened into bone. Your baby will sleep longer stretches at night and have regular naps during the day. The baby's primitive reflex behaviors begin to disappear and are replaced by spontaneous movements. The baby's vision has also developed to the point where he can see everything within 1 meter.

6. Three-month-old baby development standards - movement

When the child is lying on his back, the adult can slightly pull his hand so that his head can exert a little force on its own and not tilt it completely backward. His hands gradually loosened from clenched fists. If he is given a small toy, he may grasp it unconsciously for a moment, and when he is fed, he will immediately make sucking movements. At this time, he would kick things with his little feet. Breastfed babies do not need to add other foods if the milk supply is sufficient. However, babies who are mixed-fed or bottle-fed should be fed once every 3-4 hours, 150ml each time, 6 times a day. The total milk intake for the whole day should not exceed 1000ml. Babies who are mixed-fed or bottle-fed should add appropriate amounts of vegetable juice and freshly squeezed fruit juice to replenish the vitamin C lost during milk processing. Generally, feed twice a day, between feedings.

During the golden period of the baby's development, if there are some abnormalities in height or weight, please don't panic and be sure to go to the hospital for consultation in time.
