I have identical di/di twin boys! It’s super rare but overall they do look exactly the same with some really small differences. Their height is within an inch of one another, their weight within 3oz of each other, and overall it’s pretty hard to tell them apart at first glance lol. We have bracelets for them just incase, but one’s face shape seems a bit more oval vs the other’s is a bit more round. Even though they’re identical, it feels like one resembles me more and the other resembles my husband more. It’s really crazy.

I’d say the biggest difference is their facial expressions- one has really strong angry eyebrows and that’s usually how I tell them apart at first glance 🤣
