Signs before a baby develops double eyelids

Sometimes parents suddenly find that their baby's single eyelids suddenly become double eyelids. This is a relatively normal phenomenon. In fact, whether the baby's eyelids are double or single has a lot to do with genetics. If the baby has single eyelids when he is young, it may change when he grows up. Whether the baby has single eyelids or double eyelids is mainly determined by the genes of the parents. It is an absolute dominant inheritance.

The baby's single or double eyelids are determined by the parents' genes

Biology believes that double eyelids are absolutely dominant, while single eyelids are recessive, so the genetic factors of double eyelids are more likely to show up on the surface of every baby. If both parents have single eyelids, the child will generally also have single eyelids. If both parents have double eyelids, generally speaking, the child should also have double eyelids, but occasionally the child may have single eyelids. The reason for this situation is because it involves issues of dominant genes and recessive genes. In other words, even though both parents have double eyelids, they both carry the genetic genes for single eyelids. When the single eyelid genetic factors from both parties pair up, the child will also have single eyelids.

There are some friends around me who had single eyelids when they were young, but developed double eyelids when they grew up; they had flat noses when they were young, but developed high noses when they grew up, and they are often mistaken for having had plastic surgery. In fact, this is all normal growth and development. What changes will a baby undergo in appearance from birth to adulthood?

Decipher the changes in baby's appearance!

1. Eyes.

When babies are born, their eyes are ugly, which makes their mothers worry: Will they always be this ugly in the future? In fact, as long as both parents have double eyelids, their children will basically inherit the advantages of double eyelids. Some babies' eyes will become double after the confinement period, while others will not change until they are in their teens.

2. Nose.

The noses of newborns are usually flat, and some even turn upside down. These are all normal. When the baby's anterior fontanelle closes, which is around 1 to 1.5 years old, the baby's nose will accelerate its growth and development, and the bridge of the nose will grow out. Before this, mothers should not use their hands to pinch the baby's nose to give it a high bridge. Not only will it be ineffective, it will also hurt the baby's delicate nose.

3. Skin.

The skin of a newborn baby is red and rough, but it will gradually improve as the baby grows older. Generally speaking, a baby's skin color is a combination of the parents' skin colors, and is slightly closer to the father's skin color.

4. Height.

70% of a child's height comes from genes from his parents, and the remaining 30% depends on nutrition and exercise. Every child has different growth patterns. Some children grow early, while others grow late. Mothers must not be impatient and blindly give their children calcium supplements or height-increasing drugs.

5. Body shape.

If both parents are obese, the child has a 70% to 80% chance of being obese; if only one parent is obese, the child has a 40% to 50% chance of being obese.
