We had a mom that we followed that called to say her baby literally ate for roughly one minute with no apparent breath and was done feeding. As much as she tried the baby refused to continue eating. This baby was gaining weight and otherwise happy. During the “quick” breastfeeding, mom described forceful swallowing. While one-of-a-kind, this is what this baby did and it worked. Every baby is different.
Realize if your baby is gaining weight and otherwise pretty content, you can usually trust they know what they are doing with feeding and you can let baby be your guide.
