I think the kids won't want to go back home.

Being surrounded by loving and super fun aunts and uncles has its ups and downs.

Pros

1. Playmates are in constant supply.

Especially ones who are willing to play dress-up,

hang out in closets full of toys,

and play with the toys.

2. They make bath time even more enjoyable.

They entertain,

encourage splashing,

and take care of my least favorite part: the actual bathing.  Well, as much as they can do anyway.

I think they love the babies' bath time even more than I do.

Cons.

The kids will be bored when they go back home with only Mommy to entertain them.

If they weren't excited to see their Daddy again, I think they'd never want to leave.
