How many hours is considered average for a toddler at Nursery?
I always assumed half days were around 3 hours and a full day around 6-7, but i'm finding in our local area the half session is from 12-6pm 
My DD is 23 months and due to start but I'll admit i'm fairly nervous for her going for so long. I know I can pick her up at anytime, but just curious as to what other mums think and do.
