Ah, siblings. Steve and I both came from families of three kids, each with two older sons and then a daughter, all the average of two years apart. He was the middle child and I was the baby. Because one child wasn’t enough for us and three was too many, Steve and I settled on two. Our daughter is four years older than our son. They are our (very) happy medium. Statistically, the gender and age difference make sibling tension much less common in our set up. But we have our off days, trust me.
