Infant I&II and Toddlers
We have two infant rooms and a toddler room (16-24 months).  One infant room for non mobile infants - those too young to sit up and those sitting but not yet strong enough to crawl.  And another infant room for mobile infants (crawlers and walkers) who are too young for the toddler room. 
We have separated these two classrooms as the development needs for these children are very different.  The non-mobile infants are usually on their own schedules and are fed on demand, where as the older infants can be on similar schedules and may have started some self-feeding.  The non-mobile infants require more holding, rocking and soothing, while the older infants need more things to pull-up on, room to explore and get stronger. 

The toddler room is a transition room between infant and turning two.  The toddlers have different motor skill development needs, their communication skills are developing more rapidly, they are more self-aware and can be more assertive.

Preschool:  Junior Preschool, Preschool, JK
There will be a class room for each age grouping.  The emotional intelligence development starts to take off with these preschoolers! 
Two's:  Focus on respect for self and others, sharing, communicating with words, as well as fine motor skill development, memory and recognition, learning to color and scribble.  Starting to show interest in potty training.

Three's:  Still focusing on respect, sharing and communication (in full sentences).  Learning letter recognition, tracing letters and learning to write their names, building social skills, and engaging in group activities.  This age group starts to calm themselves from/during temper tantrums. 
Four's:  Focus is on school readiness emotionally, socially and academically.  Emotional intelligence emphasis is on taking turns, developing the ability to wait in line, understanding how others feel, developing empathy and learning to control impulsive behaviors.  Their personality is starting to form at the age of four.
