I’m not sure what he older one did to the younger one, but the younger one sure got chewed out for her retaliation efforts...
I’m not sure specific retribution has happened for that but they’re fairly mean to each other. Another time the oldest who was 4 at the time did a ‘drive by’ and stole the 2yr old’s fave toy. The 2yr old picked up a wiffle ball bat and began to beat the 4yr old with that. In spite of the fact that the 4yr old was then more than a head and shoulders taller than the 2yr old.
The redhead doesn’t take gruff off of anyone. She does a perfect viking berzerker when she’s mad.
