AITA for treating my children equally?

I (AF) recently had twins. One twin came out a girl, like I wanted. The other had the audacity to be born a boy.

Despite his betrayal, I have done my utmost to raise my two children with rigorous equality. Each child has an equally sized bedroom, with identical furniture. A bed (princess bed) for my daughter and a bed (sleeping bag) for my son. A dresser (antique armoire) for my daughter and a dresser (pile of laundry) for my son. A dollhouse (mansion) for my daughter and a dollhouse (broken mansion) for my son. A meal (lobster thermidor) for my daughter and a meal (cereal) for my son. And so on.

I don't just stop at (separate but) equal material possessions, either. Every time I pay attention to one twin, I pay equal attention to the other.

I started early. For example, when my twins were toddlers, I taught my daughter to walk, talk, and stack blocks. Between these lessons, I taught my son how to say sorry, so he can apologize for his existence.

Now that they are children, I make sure to give them equal feedback on their social, mental, and creative growth. Every time I praise my daughter's progress, I inform my son on how ti improve. I even make sure my son gets a valuable education in housecleaning while I'm helping my daughter with her homework!

Despite my rigorous attention to equality, my son cries a lot and is often tense. He recently started wearing a bear suit. Have I done something wrong? Did I perhaps coddle him too much as an infant?
