When we finalize M's adoption, we get to choose what her legal name will be. We decided a couple months ago what her name will be. Her birth name (that we've been calling her) will become her middle name and we are giving her a new first name.
We didn't want to call her by her new name when J was still with us as we thought that would be confusing to her. M was called by a different name with the other foster family, so J already had to make the change once.
Now that J is gone (miss that girl!), we've started using both names with her to start getting her used to her new name. It's been a little weird, but we really think the new name suits her.
I just hope she's not scarred for life being called by three different names before she's even 2!
I'm sorry I can't share the name here. Until she's legally ours, I can't share her name or photo online. If you really want to know (and I know you in real life) send me an email and I'll share.
