Brooklyn is a natural. She is the most loving, attentive, gentle big sister. 

I could not be prouder of her.

She is helpful, thoughtful, loving and like I said, a natural. 

She is always eager to hold Wyeth in the "burping position" as she calls it. 

Slightly less happy when those burps emit spit-up. 

Her little brother seems pretty happy with her too.

It's a good system.
