I don’t know what to do with this money

So when my grandmother was alive she would give me money for my birthday and just because sometimes. This money is years and years old - this was when I was in my teens and I’m 34 now lol- I think it’s about 800 dollars all in all The thing is I never spent what she gave me and when she died I decided I’d never spend it unless something really important came along. That way it would be good fortune- heavens fortune. And when the time came it was actually all covered by my in-laws So it’s pretty sentimental Not sure what to do with it as it’s just sitting there as it has for years and years I thought maybe I can gift it to my 8 month old. And she’ll have access to it when she’s older. Any other thoughts? Or is this a good idea? Let me know 😊🩷
