No, you're perfectly fine right now. Sometimes it's good to fight, but you also need to establish more rules if this keeps up and occurs more often!
I also watched on Tyra the other day about sibling birth order. lol That's something to look into too, but I doubt it would exactly match your own children.
Good luck, and don't worry. Being a child and being a parent is tough work!
