We dutifully went along to the nursery christmas play this morning. Then sat with DS to watch the whole thing as he refused to join in.
We ate mince pies, chatted with the other parents then left.
I'm not sure how to feel about it, especially as he'd spent all week asking us to make him a cow costume (which we did), then spent all morning dressed as a cow (leaving fluff all over the house), then refused to be any part of it.
