I finished the jacket just before the new girl showed up. It's called the Latte Baby Coat, and my Ravelry notes are here. It's sized for a 3-4 year old, but I wanted it to be oversized and fit the boy for more than one year. Besides, oversized things on little kids are extremely cute.
The hat is part of an attempt to keep something on his head for more than a couple of minutes. He doen't like to wear hats, but he really, REALLY doesn't like to be cold either. I thought something that tied on to his head would be helpful. Unfortunately, he looks like a girl in a bonnet with it on. Still, it's awfully cute. Here are the Ravelry notes.
