Longer times between feedings?

My baby is 11 weeks & i’ve read that sessions should only be getting shorter overtime, not further apart, but my girl seems to be hungry much less frequently lately. I find myself trying to feed her a little bit before she even acts hungry just because it’s been over 2 hours already & that’s when she’s usually hungry & she’ll eat for about 2 minutes. Should I even be doing this? She’s still having plenty of wet diapers so I know I probably shouldn’t worry but of course I am. Is this normal or has anyone else experienced this?
