Parents' disagreements and differences directly affect the children and their mindset no matter what age they are. Parents need to be polite, humble, loving, and caring toward each other to set an example to follow for their kids. No matter how good a parent you are as an individual and how close a bond you share with your child as a parent, children need a complete package of a gentle and interactive family to grow and nurture.
As a couple, you might be just having regular health and sharing your point of view but be aware of how your child is taking it. Either make them understand that this is very normal or avoid doing it in front of your child because even at this age when my parents have an argument or difference of opinion it disturbs me.
Children are very fragile and their hearts and minds are even gentler and raw than their physique. They do not understand the logistics, opinions, and conversations of what we are doing, they only understand the gestures. So be nice and conscious about your behavior with each other as parents when your child is around you.
