My little sister turned 13 at the beginning of March, and my mom had her birthday party a few weeks ago. I made her a Twilight cake (with lots of help from her), since she is really into the Twilight books. I can't believe that my little sister is 13......that makes me 26, since I was 13 when she was born. I know...it is crazy!!! My sister has really been a big help with my kids lately, and Merayya LOVES her! She will not leave her alone!
