What about the fat doll?

Very bad. In the past, people had a wrong idea that chubby dolls looked cute, but it would be bad if they exceeded the normal standards and scope of children of this age. The normal weight of a 6-month-old boy is 7.8 kg+- 1.9 kg, and the normal height is 67.8cm+-5.4cm.. Your baby doesn't know whether it is a boy or a girl, but it is basically within this range. Suggestion: Go to the Children's Hospital to check up the baby, or try to control the baby's mother's diet and don't eat too much.
