Am I the jerk for still using the baby name I told my sister I was going to use, despite her using a variation of it first.

I am a 35-year-old woman, and I had my first daughter in September. While I was pregnant, my sister, who was 38, was also pregnant with a boy.

In reality, she was pregnant with twins, a boy and a girl, but thought it would be a fun surprise for everyone.

During that time, I told her that I planned to name this baby after our mum, Colette, and my husband's mother, Coral.

Both names start with Coe, and I think Coco is an adorable nickname.

She told me the name they picked was a surprise, and they didn't want to reveal it until the baby was here.

Lo and behold, her twins are born in August.

Everyone is super surprised that it's twins.

She names them Cole and Letty.

I didn't think much of it, except that it was really cute and sweet that she clearly named them after our mum.

When my daughter was born, I followed through and named her Colette Coral.

We almost exclusively call her Coco.

My sister is very annoyed that I followed through with the name and brings it up all the time,

how ridiculous it is that three of them practically share a name.

It's also confusing if full names are used.

I will admit that.

Despite me telling her my entire pregnancy,

this was the name I planned to use. I even had stuff made with the name. She though ensures

everyone knows her babies were born first. Honestly, if she told me months ago that she planned to

use Cole and Lettie, I probably would have pivoted, but she never said anything.

Heck, even if she told me she was using coal, I would have re-evaluated. I'm currently debating,

legally swapping Coral and Collette simply to keep the peace, but that feels an awful lot like
