I had a massive stroke when I was 10 months old. I am now 54. There is a lot of websites to look for information.
Google search: infant stroke or prenatal stroke

There also a lot of groups and pages on Facebook.

Find some things she can use to strengthen her hand with at home. Like a squeeze ball, silly putty, puzzle type boards (for hand coordination).

I too do not have full use of my right hand, and had the same prognosis as you. Never had speech issues when I was young and always did very well in school. I like the sciences and arts. Have a computer tech certification and love photography.
