is my daughter a super genius?? j/k - but I'm impressed

We were looking at pictures yesterday, which we really don't do very often.  But, there was one pic of DD at her birthday party (from December) and my mom said "who's that?"  and DD said her name and then she said "with my butterfly cake" "my birthday" - ummm - wtf?  That was 7 months ago. ..

I was pretty blown away that she remembered that. 

I know she's starting to understand yesterday/tomorrow and she'll talk about things correctly from yesterday, etc. but still - wow
