Are the words we say to a baby before they can even understand them, a good indicator of how the kid is going to turn out?

Had visitors last night. One of the girls is 21 and has a 9 month old baby. She must have called him a “brat” 5 times while they were here, told him he was annoying and just said so many negative things. He wasn’t a brat and he wasn’t annoying. All he was doing was what 9 month old babies do…standing up hanging on to tables and chairs, getting into stuff that was left in his reach, crying once in a while for whatever reason. She, however, was engrossed in her phone the entire time and didn’t appreciate being interrupted by her responsibilities.

There was a term that was in use when I was a born again Christian….“Speaking it into existence.” I think that is a good term.
