Many parents find that their babies are born with single eyelids, but sometimes they can develop double eyelids when crying, especially for sick babies whose eyes can easily become double eyelids. This is closely related to genetic inheritance. If both parents have single eyelids, the baby will definitely not have double eyelids. If one parent has double eyelids, the baby is likely to have double eyelids. Do double eyelids also need to go through a growth process? Are there any symptoms? Let's take a look with the editor:
What are the signs of a baby having double eyelids
1. Biology believes that double eyelids are an absolute dominant inheritance, while single eyelids belong to recessive inheritance, so the genetic factors of double eyelids are more easily manifested on the surface of each baby. If both parents have single eyelids, then the child should generally have single eyelids as well. If both parents have double eyelids, generally speaking, the child should also have double eyelids, but occasionally there may be single eyelids.
2. The reason for this situation is due to the involvement of both dominant and recessive genes. That is to say, although both parents have double eyelids, they both carry the genetic factor of single eyelids. When the genetic factor of single eyelids carried by both parents forms a pair, the child becomes a single eyelid.
3. There are some friends around who had single eyelids when they were young, but later became double eyelids as they grew up; When I was a child, my nose bridge collapsed, but as I grew up, it became a high nose bridge and was often mistaken for plastic surgery. Actually, this is all normal growth and development.
Decrypt changes in baby's appearance
1. Eyes
At birth, babies have ugly eyes, which worries mothers. In fact, as long as both parents have double eyelids, children will basically inherit the advantages of double eyelids. Some babies' eyes will become double after giving birth, while others will not change until they are in their teens.
2. Nose
Newborns have a collapsed nose bridge and even an upturned nose, which is a normal phenomenon. When the baby's fontanelle is closed, around 1-1.5 years old, the baby's nose will accelerate its growth and development, and the nose bridge will grow out. Before that, mothers should not use their hands to create a high nose bridge for their babies.
3. Skin
Newborns' skin is usually red and rough, but as they grow older, their skin gradually improves. Generally speaking, the color of a baby's skin is neutral to that of their parents' skin and slightly biased towards their father's skin tone.
4. Height
70% of a child's height comes from their parents' genetics, while the remaining 30% relies on nutrition and exercise. Every child has a different growth pattern. Some children grow up early, while others grow up late. Mothers should not be impatient and blindly supplement calcium and take height increasing drugs for their children.
5. Body type
If both parents are overweight, the probability of the child being obese is between 70% and 80%; If only one person is obese, the child has a 40% to 50% chance of developing obesity.
When Baobao was first born, his little face didn't look as good because he was immersed in amniotic fluid for too long. However, over time, it was discovered that the baby was particularly cute, with tender and smooth skin. Whether it was a single eyelid or double eyelid, it was very cute. This was something that the baby couldn't decide for themselves. The body and skin of the baby were influenced by their parents, and their genes were very important. As the baby grows older, they will find that they are becoming more and more beautiful, and more like their parents.
