"Ga Ga" Attack?

Not sure what happened to Little Arielle but she seems to be afraid of something. Kept saying "ga ga" and kept patting her chest with her palm. Not sure if there was any creatures or insects that went near her? I looked around and there was nothing in sight! I hugged her tight and said, "Mummy and Daddy are here, don't be afraid!" Hopefully the fear will subside....
