DS's birthday is quickly approaching and we have decided to have the party at a free admission amusement party that is about 40 minutes away from our home. I'm looking to order the invitations and am undecided on what time to have the party. Would 5pm be unreasonable? Most parties we have had are 1-3 or around, but DS naps from about 1-3:30pm and I'd like to avoid birthday madness/skipped nap melt down mode. Those in attendance will probably be mostly family and our friends, my husband stays at home with him so he doesn't have too many friends his age yet. Having it later l also mean it's cooler out and we can enjoy the park all lit up for the nighttime lights and such. His bedtime is usually anywhere between 8-9:30, so I'm not too concerned there. I am the worst at knowing party etiquette, is this going to get me side eyes?
