The only piece of advice the sellers gave us when we bought this house was to expect a lot of trick or treaters! We apparently didn't take them seriously enough, since we ran out of candy towards the end. Aside from that though, the night was a huge hit. We didn't go out, but dressed the girls up to hand out candy. I wasn't sure what Emily would think about all the kids coming to the house, but both girls loved it! Once Emily got the idea, she did all of the candy-handing on her own, only running away from the door to find me if there was a particularly scary costume (leaving the poor kid standing on the doorstep). In between visitors, my shy child leaned out the front door, yelling "Happy Halloween! Come over here and get some candy! Do you want any chocolate?" She didn't even complain about not eating the candy, and was happy with the one little piece we managed to save her at the end. Adara crawled/walked/danced around, grabbing candy out of the bowl and throwing it in delight, and even putting a few pieces in bags too.
