Is there an optimal total amount of time for preschool; either days or hours per week?
My 3 y/o son has no siblings or age related peers in our neighborhood. He goes to preschool 2x a week for 2 1/2 hours and thrives. I requested another day or two but the staff felt he has the optimal schedule. My research leads me to believe a 3 or 4 day schedule is fine and not excessive; especially since he begs to go. Any research to suggest an optimal amount of days or hours per week?
