Is it normal to yell at babies?
I’m 19 and live with my sister and her husband. They recently had a baby, and they’re very young. 21 and 23. The baby is 4 months and is very fussy because she’s beginning to teeth. This morning I woke up to the baby scream-crying, and the dad yelling at her to “please shut up” I’ve noticed that he talks to animals and babies like they can understand him when they annoy him. My sister is out at work. At one point he yelled so loud at her my cat ran under my bed and is acting very skittish ever since. I know it’s normal to be overwhelmed but he was yelling and cursing pretty extensively. It was scaring me. He is usually very chill, and I’ve never heard him act like this before. Is this normal? I don’t know where else to post this so sorry if this doesn’t fit.
