My Ds took a long time to settle at nursery, not helped by being off frequently with illness. He settled well in the end and although still grumbled in the morning, was off playing before the door even shut. He had a major wobble when a new staff member started and it took a few weeks to settle down.
He's now 2 and moved rooms, and he is heartbroken. He does not do change at all. Even on holiday last week he asked to go home to his cot at night. To make it worse I work at his nursery (never go into to him in the day though) and I can hear him crying. . It SO hard.
Someone tell me it will get easier (I know i should know this but its different when its your own)
