Does anyone know what this is?

Ma

So, my baby has these "cramps", I don't know how to explain that better. Her whole body is tense. She put her knees up and here hand in front of her chest and stays like that for a few seconds (between 2 and 10 I think).

I thought at first it was a sign of tiredness but that's not always true.. We to her doctor today and now we have to go to the hospital the day after tomorrow to get her brain checked. Will have to stay there for at least one night.

I'm soooooo scared! I'm crying non stop and feeling guilty wondering if I had done something wring during pregnancy that causes this. I'm freaking out over here..

Did anyone of you ever experienced something similar with your babies?
