Baby's arms shake. Reason for concern?

So I've tried to eat healthy since eating SUPER yummy bagels a friend brought over this morning from Brueggers's Bagels. Oh gosh. She left them here too, so I ate them! I had a total of 2.5 bagels. That's about 700 calories.

LOL.
Sort of...

I'm a carbohydrate freak.

So for lunch I had 2 hard boiled eggs, a garden salad with balsamic, and some grapes. I also had a trail mix bar.

I'm hungry again.
I think I'll have a sandwich to hold me over until K gets home.

I simply can't get full these days.
I'm trying to eat healthy so the baby gets all she needs as far as vitamins and such go.

So I've worried just a little about her because she sometimes shakes her arms...almost like a tremor. From all I've read, it is due to an immature nervous system. I read that if the shaking stops when the arms are touched, then it is ok. However, if not, then there is reason for concern. Hers stops when I touch her arms.

I'm going to ask the doctor at our next appointment and I'm not going to worry too much until then.

She's fussing...gotta run.
