Temper, Temper!

I saw something new in my son today - my sweet little four month old had a clear show of temper. He scrunched up his face in anger and began to scream. What brought this on, you might ask? It was all because the pacifier fell out of his mouth and I wasn't quick enough to return it to him! This is especially surprising because my son rarely takes a paci. But today, he was attached. It just makes me wonder what I'll be in for when the terrible twos arrive.
