LO throwing tantrums?

Is anyone else's LO throwing a fit when they you take away something they grabbed but shouldn't be holding? For example, I was cleaning and my son grabbed a piece of paper towel (clean not used) and tried to put it in his mouth. I gently took it away and he wouldnt stop crying and was so irate. He has been doing this quite a bit now.

My son is 6 months on the 3rd.
