How do you do preschool with two working parents?

Hello fellow dads! My 3 year old son is going to be able to attend the local preschool in August. We took a tour and are very excited for him, it looks like a great place for him to learn.

My question is, the full day hours are 830-230 how do people with two working parents deal with the pickup time? We both work “normal” hours getting off at 4 and 4:30. He is currently going to daycare that ends at 5 so we can make it work. Has anyone gone through this and what have you done?

We asked and they do not have any extended day or care programs. Do people just have family members take care of their kids for those couple of hours?
