"Wind beneath my wings"

Little dude and the baby at 2.5 years old and 3 months old respectively

Did you ever know that you're my hero?

And everything I wished I could be?

I can open the fridge door and eat cheese

'Cause you're the wind beneath my wings

The universal rule applies: limited resources, unlimited wants. So it will happen that siblings fight over stuff. You can't have one each for every single thing. Two identical lego sets just so that each kid can have that particular figurine or animal? What about buying two sets of toy food so that there are two onions to prevent the kids from fighting? Don't think so. The siblings fight, learn about sharing, try to practice it, fail, then try again. We're progressing.

The baby, though she complains about her brother pretty frequently, really adores him. He's her hero. He can literally open doors for her. And get things beyond her reach. No room in the house can be kept out of bounds to the fourteen-month-old with her brother around. You want the calculator behind that closed door? I can open the door! It's up on the table? No problem! Big brother will get it.

Best of all, little dude can take the baby to the kitchen and open the fridge door. My cubes of cheese have been disappearing fast. Little dude helps himself to the cheese, but doesn't forget to peel open the wrapper for his sister to have some too.
