One of the many benifits of a Home Daycare is the interaction between the children. Infants have a chance to learn, watch, socialize, and play with older children. They also learn to look for them for comfort and support. They know that the older children will be here for them.
The older children benifit as well. They learn to communicate with someone who might not be able to verbally communicate back. How to care for another who might need help. Helping out the adults to care for the younger children. They learn to be leaders and a role model for the younger children. I remind them that the toddlers are watching and learning from you. They want to do the samethings you do. If you take toys away from them, then they will do the same to you. Is that what you want to teach them?
The home daycare provides this interaction. As the children are sharing the same space and environment.
