The venue we're having DD2's first birthday party has two time slots we can choose from:

10am-12pm or 1pm-3pm

I can't decide which one to go with because DD2 still takes two naps so if we go with 10am she will have to skip her morning nap and I'm afraid she might turn into miss cranky pants at the party. On the flip side, 1pm-3pm is DD1's nap time (she's 3.5) and she regularly naps for 2 hours. Most of the kids attending are between ages 1-5. Which time slot would you choose?
