how often should baby eat?

my mom told me today that she’s never saw a baby eat so often. My LO is 6 months old and is still eating every 2 hours and has been this way since birth. she even night feeds every 2 hours. sometimes she cluster fed every 30 min in the beginning.. but this kind of discouraged me as i’m not doing something right and I expressed this to her and she didn’t mean any harm but she’s never breastfed so she doesn’t really know much. she’s the one pushed me to continue after I wanted to give up a lot of times. but I thought it was normal for her to still feed this way?
