Green-Eyed Monster

So Selah has developed the "Third Child Syndrome" - namely, that SHE'S the baby, and not you. And by "you" she means Kaity and Joe. Daddy and Mommy are not actually allowed to snuggle the big kids with suffering the consequences of Selah's squeals and complaints.

Here she's just verbally expressing her angst over Joe receiving the attention.

Now she has moved on to the physical stage of yanking on Joe's pantleg, attempting to dislodge him.

Sweet victory! Smiles abound.
