I wrote a post about what it's like to be a twin... tl'dr, it's not easy.

I actually think though that it's also very hard to be siblings with a twin or triplet (or other multiple). It may actually be harder, but I have no way to know. Multiples tend to be allies, and so it's not uncommon to feel ganged up on or left out.

Is anyone siblings with twins or triplets? What was the experience like for you?
