After 6 months, the birth weight can be calculated according to the formula, which is birth weight+month age X500.

Whether breastfeeding, mixed feeding or artificial feeding, six-month-old babies basically have to start adding complementary food. When adding complementary food, it should be added from less to more, from fine to coarse, from one to more, and in small quantities. When you start adding, you should add a single variety. Add a complementary food and observe it for three days. Only when the baby is not unwell can you add another complementary food and add it gradually.

The vast majority of children have passed the prone position at this age and can support their bodies with their hands, so most babies can take the initiative to turn to voice or talk and imitate their parents' voices.

Children of this age can sit without hands, and half of them can sit without hands. Some children may need to support a little with their hands, because the waist strength is not enough. I can take the initiative to put what I can get into my mouth, and my left hand will pass it to my right hand.
