Among the thousands of thoughts and questions we ask ourselves when we are pregnant, the color of the baby’s eyes is one of the most disputed. Even more so when a parent or grandparent has clear eyes. The desire for the baby to inherit the beauty of the blue eyes is inevitable. But do you know what defines the baby’s eye color and what factors are important for that definition?
In the first days of life, the baby’s eyes are usually grayish-blue, which further increases the expectations of family members. As the days go by, this color changes and becomes blue, green or brown, getting closer and closer to the color it will really have, so don’t be fooled when you encounter totally light eyes at birth, everything can change over the months. The responsible for determining the color of the baby’s eyes is the melanin existing in the iris of the eyes and when newborns the quantity is still very low and as the color is regularized, it is defined. The iris is located right behind the cornea where the pupil is in its center, whose color is always defined in black. Some genetic problems can also cause changes in the color of the iris, such as albinism, which due to low levels of melanin can result in pink eyes,
Usually the baby’s eye colors start to change and get closer to what will be around 3 to 6 months of life , after that it ends up defining itself completely until reaching the first year of age. The shade of the eyes is completely genetic and determined by hereditary factors, but unfortunately it is not possible to state the color of the eyes that your child will have, after all they are probabilities and that may have margins of errors and changes. The gene that determines the baby’s eye color is prevalent as soon as there is fertilization! DNA already defines as soon as the two cells (sperm and egg) meet. The influencing factor is a parent’s dominant gene. If it is blue, your baby will have blue eyes, if it is brown, it will be brown, and so on.

How to Calculate Baby’s Eye Color
As we have already mentioned, the baby’s eye color is defined through hereditary factors where the genes of the parents and family count a lot. So it is possible to have a prediction of the color of the eyes that the baby will be born, but we emphasize again that it is not 100% guaranteed.
- Father and mother with brown eyes have a high chance of the baby being born with brown eyes;
- Father and mother with blue eyes have a good chance of the baby being born with blue eyes;
- Father and mother with brown eyes, but with one of the grandparents with blue eyes, there is a chance that the baby will be born with blue eyes;
- If one parent has blue eyes and the other has brown eyes, the dark color is more prevalent.
The miscegenation of races and ethnicities makes each time the color of babies’ eyes is born different from each other, as well as the tone of their skins and hair. Some countries or cities group larger numbers of people with lighter skin, blond hair and lighter shades of eyes, as in the case of Germans and in the case of Brazil, people residing in the South of the country.
Taking advantage of the space, I would like to tell a novelty to our pregnant readers. Famivita and I, thinking about the nutritional needs and also difficulties of women during the gestational phase, developed a complete gestational multivitamin with all the vitamins and minerals important for fetal development with a differential of the other vitamins, the size of the capsule. As it is very difficult to swallow capsules and tablets during the period of nausea and nausea, which in some cases can extend throughout pregnancy, we produce the vitamin FamiGesta in small capsules that are easily swallowed, the size of an MM’s. You can purchase it here our online store.
My name is Dr. Alexis Hart I am 38 years old, I am the mother of 3 beautiful children! Different ages, different phases 16 years, 12 years and 7 years. In love with motherhood since always, I found it difficult to make my dreams come true, and also some more after I was already a mother.
Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
