Hi there,
as long as it’s eating, I wouldn’t worry about anything. I find that my baby frog had some trouble catching crickets at first but as it has gotten older, it’s getting much better at it. You can even try using feeding tings, they work great and the frog will quickly come to associate the tongs with food which will make feeding it a lot easier when it gets older.
Your setup sounds perfectly fine for your little it.
good luck!
