Yes, snoopy, you are correct. I have DD13 and DS10 from a previous marriage.
They are very excited, as am I. It will be nice to have some extra hands around!
DD has been having a lot of fun shopping for cute little girl things and DS is very excited because he'll get to "push the stroller when we go to Disney"!
That's always his job when we go with our friends who have small children. He's very excited to now be able to push his own sister!
