According to the Ministry of Health's Reference Standard for Growth and Development of Children under 7 in China, the standard range of height and weight of 6-month-old babies is:
Male baby: height 61.4-75.8cm; Weight is 5.97-11.72kg; The head circumference is 39.8-47.7cm.
Female baby: height 60.1-74.0cm; Weight 5.64-10.93kg; Head circumference 38.9-46.5cm
Affected by various factors, there will be obvious individual differences between babies. As long as it is within the normal standard, parents need not worry too much. For example, in life, some babies can sit for a while without help, and some babies need help to sit still. As long as the baby is generally in good condition, don't worry too much.
Growth and development of 6-month-old infants
After six months, the baby can respond to the sound and the change of volume. Parents can often "talk to themselves" in front of their babies to see if they will interact with foreign voices.
After 6 months, the baby can add complementary food, but it should be done step by step according to the baby's growth, so that the baby can make a smooth transition from liquid food to solid food and fully absorb nutrition.
In the development of fine movements, 6-month-old babies like to play with their bodies curiously, grasp their feet with their hands, change toys from one hand to the other, like to repeat certain movements tirelessly, and often deliberately throw things in their hands on the ground, pick them up and then throw them out. In addition, he often grabs an object around him, pushes it away and grabs it back.
