concentration

So I'm feeling sheepish, because right after I posted about Silas not being an "easy baby" anymore, he transformed back into the angel child I once knew. I guess we might have been going through a 6-week long not-feeling-good-and-teething phase?

Anyway, last night he was playing with his stacking rings in his room for like 40 minutes, doing this over and over. I think he has it down to a science now.
