Does anyone else have a baby that doesn’t like to eat?

Me

My first son was a big eater and big comfort nurser. He was always on the boob. My new baby born in July though eats very little. Very rarely will he cry to nurse. I basically have to convince him to nurse and even then he nurses for maybe 5 minutes and is done. He is gaining weight. Has tons of poopy diapers and pee diapers. He’s 2.5 months old and weighs 13lbs, and was 7lbs at birth. So I know he is getting enough, but he just doesn’t seem to enjoy eating and he NEVER comfort nurses. He wants his paci for comfort.
