What Should U Do If You Gave A Kitten An Adult Food?

I have a kitten that is 4 weeks old. I recently made a mistake and gave her an adult food instead of proper kitten food. She doesn’t seem to be sick or anything, but I don’t know if it may cause other problems in the future? Or will she grow out of it? What should I do next?!

How much money would you need to buy your first dog? How much would you spend on him yearly? Would you go for show dog, working dogs etc.? If so what breed(s) would fit best into your budget and lifestyle (if any)?
