El que nace barrigon, ni que lo fajen chiquito
This proverb means a person's nature or character is permanent and impossible to change, similar to saying a leopard cannot change its spots. It implies that if someone is born with a certain character, no amount of correction or discipline will fix it. The word barrigon is sometimes replaced with maruton, which refers to the navel. (The literal imagery refers to the practice of wrapping a baby's abdomen in a sash to shape the body or prevent a protruding navel).
That kid is never going to change, el que nace barrigon, ni que lo fajen chiquito. And the mom thinks he is an angel and it is just a phase, but el que nace barrigon ni que lo fajen chiquito.
