Sim hates children, but it's not working out the way I was expecting

Lily definitely gets tense around children in my game (not so much with toddlers). Destroys doll houses and hates anything child related toys and such in a room she gets tense. She yelled more at her child sim than anything. Surprisingly she was just a little bit better to the toddler well other than when they started crying or throwing a tantrum.
