What are the Developmental Milestones for a Baby at 2 Months and 10 Days?
Infancy is the golden period of rapid physical development in a person's life, so during this time, parents often notice that their babies grow very quickly. There may be differences in the physical development standards of babies at different ages, and these standards are important criteria for evaluating whether a baby's development is normal. So, what are the development standards for a 2-month-and-10-day-old baby? Here are some key points:
1. Height and Weight
For male babies at 70 days old, the height range is 52.2 to 65.7 centimeters, the weight range is 3.94 to 7.97 kilograms, and the head circumference range is 35.2 to 42.29 centimeters. For female babies, the height range is 51.1 to 64.1 centimeters, the weight range is 3.72 to 7.46 kilograms, and the head circumference range is 34.5 to 41.8 centimeters. At this age, babies can make gurgling or cooing sounds, their eyes can track objects within their visual range, they notice their own little hands, and they can lift their heads for short periods. Some babies can even lift their heads and shoulders when in a prone position and can support their body weight with their legs.
2. Vision
By 70 days old, a baby's vision has also entered a new stage of development, and they can vaguely see moving objects. If a mother holds a bottle in front of the baby and moves it, the baby will follow it with their eyes. It is recommended that mothers buy brightly colored and moving toys to attract the baby's attention, which can help promote their intellectual development.
3. Hearing
In addition to vision and gross motor development, a baby's hearing also continues to develop at this stage, and they become particularly sensitive to sounds. If there is a sound nearby, the baby can accurately determine the source. They can also respond to their mother's coaxing and know to smile back. It is beneficial for mothers to communicate with their babies more during this stage to promote mother-child bonding.
