it's just filler with no actual nutritional benefit and only constipates them.
Some kids are just little chunkers, lol. My first two ate constantly the first year. Increasing the amount per feed only caused spitting up, not less eating.
Exactly this! My own baby was super chunk and wanted to nurse all the time and would barf if I fed her more. It was a comfort thing and an oral fixation thing. Pacifier saved me.
At 20lbs this kid does not need more food!
