You can always check if there is research that can be joined on the subject.

The benefits of joining research: 

A: It does not involve payment and the treatment costs in private care can be quite high.

B. Ensuring safety in research is higher than elsewhere.

Disadvantages of joining research: 

A. Children may be disqualified from research due to certain parameters (like unit size, genetic disease, the child's IQ, etc).

B. Waiting for research can take quite a long time.

C. In the study, the child is given one dose of cord blood/stem cells and one dose of placebo six months apart. It is not known what treatment the child will receive at a given time.

Children generally won't be allowed to participate in an experiment in a country that does not use their native tongue since it won't be possible to evaluate the child's speech improvement.
