It’s easy to use a baby as a scapegoat. A baby has not wronged a single person, and if you have a baby (especially a fresh one), you can claim that every negative act done towards you is in turn an act against a poor, sweet, innocent infant. 

We all know that’s a load of nonsense. If I decide not to be in someone’s life because they wronged me, their baby is not going to know a difference between a life with me or a life without me. Of course, this logic doesn’t apply to the parents of said baby. If a mother cheats on the father of her baby and he leaves both of them never to be seen again, that baby is going to be emotionally damaged because they’re being punished for something they didn’t do. But if a friend or an extended family member chooses not to engage with a babies parent for whatever reason, it’s well within their right and usually morally sound.
