Searching for a child / baby

Hallo All, I am a single woman, 43 years old, Swiss and live in Switzerland. I would like to adopt a child (if possible up to a maximum of 5 years old). Have not yet decided on a country but open for all countries. Do you know a lawyer with experience for an internationsl indipendent adoption or a woman who wants to give her baby / child free for adoption. I can give the baby / child lot of love and a nice home here in switzerland and Support for the mother during this time and later. Many thanks in advance to all who bring me one step further. Best regards,
