When Silas starts to lose it, his little arms start slapping his legs, one after the other, like he's drumming. Then the screeching begins. Holy hell, the screeching. It's so loud sometimes that I have to remind myself that he's a baby, because otherwise my temptation is to tell him to shut it. Generally he's overtired, wants to be picked up or needs to nurse...or all three.
There he goes now. Must.Make.Screeching.Stop.
