Our 4 year old just started junior kindergarten, which is all day, 5 days a week. He use to take 2-3 hour daily naps, and has been fully potty trained for 2 years. Within the first 5 days of school, he has started pooping his pants, both at school and at home! He is expected the wipe his own bum at school, which he struggles with. The teachers are unable to help them at that age, due to ' legal ' reasons. He is happy, enjoys school, and doesn't cry about going.
