There are usually only two types of eyelids: double eyelids and single eyelids, so a baby's eyelids are either double eyelids or single eyelids. Recently, a mother discovered that her baby's eyelids are a pair and a single, which has made her a little confused. She wants to know if this situation is normal for her baby, and whether it can change from a pair to a single? So let me tell the mothers below.
Whether a baby has double eyelids or single eyelids is actually determined by the genes of both parents. Double eyelids are inherited in a dominant manner, while single eyelids are inherited in a recessive manner. If both parents have double eyelids, most babies will have double eyelids, but there may also be cases of single eyelids or single eyelids. Therefore, it is normal for babies to have double eyelids and single eyelids, and mothers do not need to worry.
The reason why some babies may have single eyelids or a pair of single eyelids is that both or one parent carries a genetic factor for single eyelids. If both parents carry a genetic factor for single eyelids, the baby may have dominant single eyelids. If one parent carries a genetic factor for single eyelids, the baby may have a pair of single eyelids. For babies with a pair of single eyelids, their eyelids will continue to change during their growth and development, and they may become double eyelids or single eyelids.
But if the baby's eyelids are swollen, it should be taken seriously. It may be caused by conjunctivitis, stye or chalazion. At this time, the mother needs to take the baby to the ophthalmology department of the hospital for examination as soon as possible to find the cause of eyelid swelling, so that the doctor can treat it accordingly. After the eyelid swelling subsides, the eyelid will return to normal.
