What looking at other daycare setups does is give us ideas. We normally have identified an area that is an issue such as separating babies from older kids and then looking at what others have done gives us an idea of how we could rearrange our furniture to accomplish the same thing - putting the shelf on it's side makes a half wall instead of a tall one - but sometimes it takes seeing that to have one of those oh yeah moments why didn't I think of that. It is especially good for those just starting out because it also gives them an idea of what are the most common toys and activities you see from daycare to daycare so a good way to make a shopping list of toys and furniture you would like to have.
