They are there to teach the preschoolers and to extend preschoolers' Sunday School learning experience all morning long. One of the best ways that preschoolers learn is through relationships with the adults that care for them. Preschoolers should be our primary focus when we are with them. Teaching is taking place and no teacher wants to be interrupted when they are teaching. Speakers may cause a teacher to miss out on the joy of seeing the world from the perspective of a preschooler.
Speakers add to the noise level of an already active room.
Speakers may distract the teachers and accidents are more likely to happen. Speakers may communicate, to parents and prospective members, that what is going on the worship service is more important than caring for or teaching their child. You are probably not alone. Adaptations are provided for many activities in the leader guide. You know your group of children better than anyone.
