Feeding a child with autism at 1.2 years old

Hello) my child does not currently have diagnosed autism, but has many "red flags" that point to it. And one of them is feeding. He does not eat solid food. And I can't find any information or specialists in my country (Ukraine) who work with such children. I came across your community, maybe you can give me advice where to go or where to find information on how to teach a child to eat solid food?
