My son wasn't that different except for when he sees someone new. Being only 8 months it was very weird. Every time he saw someone new he would start to shake rapidly. Maybe it was instinct or just a mental thing.
One night my husband left to go to some sort of party leaving me with our child. Everything pretty much the same. After making Lucas sleep I went to bed too. Until it became 12:00, he start crying.
Running up to him I noticed he was shaking. He only did that if he saw someone new.
"It's just me here Lucas." The moonlight shined into the room. My shadow was on the ground but another one was there. A silhouette of a man with a knife, I wonder what my husband is doing out so late.
Our child never gotten used to him anyway...
