We've always either done DD's parties around 10-11 or 3 pm. Nap time is too precious to me to schedule a party then! When she was a toddler, we'd just go late to birthday parties scheduled 2-4. My BFF scheduled her DD's first birthday party for 1-3. She originally said 2-4, but I asked her when she napped, which prompted her to change it. Couldn't do it earlier as it was on a Sunday and people were coming from church.
