Planning a toddlers party during typical toddler nap hours. Why.

Why. Why do people with toddlers do this? Is it not common sense to maybe not plan things directly in the middle of the day??? Especially if it is an event for a small child, like between 6 months to 36 months?

Almost every time we are invited to a event for another toddler it always starts at like 1-1:30pm. What's up with this? Does this just happen to us or has anyone else experienced this?

Granted, no one is holding a weapon to our heads and forcing us to go directly when the party starts, but it is such a pet peeve.

edit: YIKES at the people getting butthurt lol This is a venting post and no where did I say all nap schedules are the exact same lol
