My mom made us a countdown chalkboard thing a few years ago. We finally managed to hang it this past summer and I found chalk markers to use on it (previous attempts with regular chalk hadn't been very successful). The boys were excited to put it to use counting down to Halloween.
Gareth wanted to be Dr. Who this year; we chose the 11th doctor (Matt Smith), since that seemed easiest to put together. However, finding a boys sports coat that is brown is very difficult. So my mom came to the rescue and made one!
As he'll outgrow it quickly, we're trying to get as much use out of it as possible. He wore it to my concert the week before and received many compliments on it.
Malcolm wanted to be a Minecraft character. Initially I was going to do the whole cardboard box Steve thing, but then remembered that our chances of rain on Halloween are pretty high here in Seattle and I'd have a very disappointed child if their costume started to disintegrate as they were walking around. So we purchased a Minecraft diamond armor costume and diamond sword. We'll get our money's worth out of it for sure, since he wore it almost daily between when it was delivered and Halloween.
Ryan took the boys out with one of Gareth's friends (who dressed up as their DND character) while I headed to rehearsal. We lucked out and it wasn't all that rainy while they were out. I'm interested to see how many more years we have of trick or treating with Gareth. I know some of the other parents of his peers are anticipating that this year or next might be the last. It's strange to think we might soon be closing out that era with one child.
