Good morning, thanks for asking at HealthReplies.com. It is true that how a child behaves, depending on how his parents behave. Through research, experts argue that a child's psychology is formed partly from offspring, or in other words innate attitudes, and partly formed from the environment, including the way parents act. This is evidenced by research that two twins who are separated from birth, when found again, are similar in nature and on the other hand, two children who are not related at all, when raised in the same way, have the same attitude characteristics.
But in your case, at 16 months of age, your baby doesn't fully understand that at that time his parents were fighting, or that his mother and father were enemies, or who was wrong, who was being hurt and the like. The infant's limited understanding at that time made him unable to understand these complex emotions.
What might happen why your baby is teary and want to cry, is because he is afraid of loud noises, and or captures the sadness that you express by crying, just as a baby captures joy when we laugh or smile with him. Your baby may feel that you are someone with whom he has a bond, is sad about something he doesn't understand, and that also makes him feel sad.
So for us, if "just" like that and that one time, the condition is that there are negative emotions that your baby will pick up on but will not affect his mental and developmental development. But of course, if you often do this until your child is a little older and understands what screaming, anger, words, violence and so on, could be mentally affected by your child. Therefore, you should hold back your anger and your husband, at least in front of your children. You and your husband can have any problem, but whatever it is, don't show it in front of your child. So, hopefully it answers your question.
