The essentials are below

How parents deal with the initial shock is very personal. You may feel powerless and sad because your child is different from what you expected. Some parents prefer to be alone, while others want to talk about it, and still, others want to know everything there is to know about the syndrome.

Impact on your relationship
A child with a disability can bring you closer together as parents. You share the disappointment and the grief. You feel responsible for your child and each other. There may be additional stress in your relationship because it can be difficult to support one another.
Siblings may handle a variety of emotions. They may feel sadness or fear and sense the tension felt by the parents. It is helpful to explain what is going on appropriately for the siblings' ages. Try to do this as soon as you think it is correct. Preferably don't say the child is 'sick' because sick children get better. Young children can also associate "sick" with when they aren't feeling well and are afraid of "catching" what their sibling has.

A child with CdLS demands a lot of time, attention and energy. You will visit the hospital regularly because your child needs extra care. It will take some time before everything goes back to normal. That is not surprising. Your life has been shaken up. You need time to find your feet again.

It is good to make those around you aware of what Cornelia de Lange syndrome entails. Our community can help you with this. On this website, you will find a lot of information, useful addresses and practical tips. You will also find other parents here - benefit from their knowledge and experience!


The daily care of a child with CdLS and the stress of doctor visits demand a lot from parents. Everything takes more time and energy. You will notice that.

However, making time for each other, or spending time alone or doing something with the other children, is essential.

Strategy for self-care
  • Acknowledge your sadness. Acknowledging your feelings is necessary to cope with them.
  • Be aware of your body. Get enough sleep and find ways to relax.
  • Take care of your relationship and your family. Make time for yourself and your partner and discuss your needs with each other.
  • Asking for help is difficult. But you don't have to do everything alone. Try to find out what kind of help is most useful for you and learn what resources are available in your area.
  • Seek help for yourself. It may help to talk to a therapist who can guide you in your role as a parent of a care-intensive child.


Cornelia de Lange Syndrome (CdLS) is a rare congenital disorder. There are several features by which you can recognize CdLS:

  • The child is smaller and (sometimes much) lighter than average.
  • The child often has long eyelashes, eyebrows, and a short nose.
  • Sometimes there are abnormalities in the arm, hand, or fingers.
  • The child is usually very hairy, especially on the back.

What does this diagnosis mean?  

Children with CdLS are different from other children. They are more likely to have gastrointestinal (GI) problems, called esophageal reflux. Almost all children with CdLS have this problem. Always ask your doctor to look at this.

Children with CdLS develop more slowly than their peers and usually have a cognitive disability. In addition, they often have difficulty communicating.

Everything will be different, but how different? There is little to say for sure about this. You will have to wait and see. In the meantime, try to enjoy your sweet, unique child.
