Which size a child wears depends on his size. A normal 3-month-old child is about 60-62cm tall, and a size 66 is suitable. If the child is fat, you need to wear size 73. If the child is thin, you can consider a smaller size.

The size of newborn babies is generally 52,59, and then the larger size is 66, which means that half-year-old babies wear it, followed by 73, which means that one-year-old babies wear it, then 80,90, 100 and so on. It may be confusing for novice mothers.

A 3-month-old baby wears size 66 clothes. However, not all babies wear size 66, and mothers need to choose according to their baby's figure and weight. Most 3-month-old babies are 55.3-69cm tall and weigh 4.69-9.37kg. Some babies develop rapidly and gain weight quickly. When choosing clothes size, we should consider the baby's development.

Babies are very active. If he wears it too tightly, it is not conducive to the stretching and movement of his limbs. If he lacks activities for a long time, the baby will easily get sick. We should give priority to loose and natural casual clothes and provide loose clothes for our baby. The baby is flexible and free to move, not only in a happy mood, but also to strengthen exercise, which is of great benefit to the baby's health. Too loose to be energetic.

Choose clothes that are easy to put on and take off, such as jackets, loose clothes, dresses, vests, etc. It is more practical for young children, while children aged three or four can choose pullovers, sportswear and so on.

Children's trousers are generally elastic belt, but some elastic belt are too tight, which will affect children's breathing and the normal development of sternum. I'd rather relax them a little.
