1 year old twins question

Be

Do your one year old twins (or did they) fight over toys? Or over you? My twins are 14 months and like to pull toys away from each other and play tug of war over pacifiers. They push each other away when they’re both on my lap. My friend who has only singeltons says my twins behavior isn’t normal and seems to be implying that I’m raising future murders. She says one year olds shouldn’t be fighting over toys yet. What is your experience?
