This too shall pass?

I'm in the midst of my second week caring for Abby and Jack by myself.

It's been an adventure.

Toddler 411 compares toddlers adjusting to new siblings to the five stages of grief. My assessment is that Abby is in the midst of "Anger", which is thoroughly depressing for me since that is only Stage 2! Luckily, Stage 5 is "Acceptance" ...

The fun behavior I am dealing with the past couple days includes:

• Odd food preferences. Abby will now only eat peanut butter (straight ... not ON anything), cookies and yogurt. The yogurt, however, she will only eat with her fingers. She is more than capable of using a spoon, mind you. Today she "ate" the entire thing with her hands. She asked for more and I walked over there to find that the yogurt cup was missing. It was on her lap. Along with half of the yogurt.
• Park or bust. Abby only wants to go to the park. Nothing else. I suggest the water table, blowing bubbles on the front porch, the library, etc. It's the park. That's all she wants.
• "SEAT!" Abby gets frustrated when she needs something, but I am holding Jack and can't get to it right away. She has started demanding I put him in his infant seat when she needs something.

There are plenty of other instances where she throws tantrums. My heart goes out to her because I know she is frustrated and just wanting my attention and I am struggling to give it to her ... even though Jack may be the easiest newborn on the planet (the boy eats, pees, poops and sleeps. Fussing isn't even a category).

This too shall pass ... right?
