You are welcome to bring your preschooler along for your tour, but it is not required.  Older children and babies that can be held are also fine to bring along. If you also have a 1-2.5 year old, please know that this age child can be challenging for this tour. The classroom is full of little things that a small child often wants to put in his/her mouth. If at all possible, leave this child with a grandparent or other care giver during your tour.
