Ahsan Allahu ilaykum. My child, who knew better, kept pushing a very large pillow in my way while I was making sujud. I would push it away but she wouldnt stop. I got angry & flung the pillow (harder than necessary) behind me. I repented. Considering all the movement is my prayer valid?

It is ok because it is for the salah, but why get so angry? Kids play.
