Definition and meaning of alone born twins

"An alone born twin (or multiple) is a person who (as an embryo, fetus or baby) in the womb has witnessed the death of one or more embryos or fetuses, what may have occurred within a few days after fertilization up to the time of birth. "

Single-born twins, lone twin, twin-alone, vanishing twin syndrome, womb twin survivor, twinless twin, belly twins, half twins, lost twin, twins disappeared, 'actually twins' ....


All terms for one and the same phenomenon.



One in ten is an alone born twin or multiple twin


Studies have shown that one in ten pregnancies start as a twosome or multiple and that in 90% of the original twin pregnancies one or more embryos die off early in pregnancy *.

Doctors or midwives often have no knowledge of this because death takes place at such an early stage of pregnancy that no echo has been made at that time.

In about one in ten women, bleeding occurs somewhere in the first four weeks, which makes her think she is not pregnant. She is then usually told that there has been an implantation bleeding. After all, she is (still) in good expectation! Only, not every woman who is pregnant has implantation bleeding; this only occurs in about 10% of the women (source: obstetric practice).

It is possible that the remains of a second embryo or fetus can be seen at a later echo. Or the obstetrician or gynecologist will find an encapsulated fruit in the placenta or a fetus papyrus at birth.
In most cases, however, a woman does not notice that there are (or has been) twins and she does not know better than that she was pregnant with one child.



You are not crazy!


The feeling that something or someone has been with you for a while but has disappeared, that feeling, that is somewhere deeply stored in your cells. It seems impossible that such an early event leaves such an impression, but in the meantime, we know from research that this is indeed possible.


In addition, twins/triplets have always drawn your attention, do you have certain feelings and you always have a dormant feeling of loneliness and lack .... do not ignore this because there may be a deeper feeling. You're not crazy!


Re-enacting the dream of the womb


Alone born twins spend their lives constantly with the 're-enactment' of being together in the womb and ultimately also the death of the other half. As it is called so beautiful in English; re-enacting the dream of the womb. This is reflected in a variety of characteristics and habits in daily life that are often performed in a subtle way. Awakening from this dream is essentially a process of recognition, becoming aware of how you do things in daily life. Realizing that you are an alone born twin is step one. From there you have a choice to take further steps.


It is good to realize that the death of your deceased twin brother or sister could have made a huge impression on you as a surviving twin. The bond that two-and-multiple twins have from the beginning (especially if there are identical twins), is special and unmatchable with other relationships. Even if you talk about embryos of just a few weeks old! The agreement to start this life together has already been made at this stage.



Feelings of emptiness and loneliness and feeling guilty unconsciously


Because of this special bond, there is almost always a feeling of emptiness and loneliness when one of the two is no longer there. Those who have not known their twin half-consciously or not at all often say they have a guilt feeling. An unconscious feeling guilty without knowing exactly why. This is, therefore, a common feature in single-born twins; feel guilty even if it does not bother them.
