The eight-month baby development standard is for you who care about your baby's health.

1, physical appearance. According to the reference value of China Child Development Standard, the weight of 8-month-old boys is 7.19-19 kg, that of girls is 6.7 1- 10.59 kg, that of boys is 67-77 cm, and that of girls is 65. The head circumference is about 45 cm. Dudu's weight is slightly below the median, but five months ago, his weight was above the average. With the growth of teeth and the addition of complementary food, the amount of milk he eats every day is not increased, but decreased. In addition, with the increase of exercise, he will turn, climb and twist. In short, he never stops when he is awake. It turns out that the baby's fat eyes are watching, but fortunately, the development index is within the normal range.

2. Great development of sports. You can sit still without support, crawl on your abdomen, stand with both hands and stand with something in your hand. Dudu can still sit still by himself in the middle of 6 months. Now he can sit still, reach the toys around him or twist his body, and return to his original sitting position. We don't have to worry about putting him on the mat and sitting on the foundation, but occasionally he leans back carelessly. In less than 8 months, Dudu has been able to support his body with his hands, while his legs are on the ground, his abdomen is off the ground and his body is parallel to the ground. But he can't crawl forward with his abdomen off the ground. He can only bend his legs and exert himself to move forward. With this crawling way, he can quickly climb from one side of the bed to the other, and with toys, he will crawl back and forth all over the bed, and he will be very good on the floor mat. Hold your armpit, you can stand upright and occasionally take a step forward, but your toes sometimes bend inward.

3. Hand and finger skills. I can tear paper with my hands, stuff things in my mouth, pour toys from my right hand to my left hand, like knocking, and find things that have fallen. In fact, I feel that these skills can be carried out as early as a month or two ago, such as putting things in your mouth and tearing paper. Now Dudu still likes to tear paper. Whenever he sees paper, whether it's toilet paper, newspaper or book paper, he will pick it up, tear it up and eat it in his mouth. Sometimes when the nipple falls off, he can pick it up and put it in his mouth. Give him a small piece of steamed bread, pour it from one hand to the other, change it back and forth, and sometimes it will fall off. Flapping is also a sport that Dudu likes. When taking a bath, he took turns slapping the water with his hands, splashing and enjoying it. Whenever he drops something in his hand, he will bend his head and try to find it. It's very interesting.
