Unhappy starting school

Our grandson started school last week also. Like your granddaughter SusieB50 he just did mornings last week. He had two days where he cried and didn't want to stay. Today was his first full day, he's tolerating it but not liking it yet.
Last night he was looking through the window and he said to his Daddy, "I wish I was a bird then I could fly away from school".
His fourth birthday was only three weeks ago. He seems so small at school.

informally, when stern teacher is not around.

Ask for advice from the teaching assistant in the first instance.

dgs was awful after his first full day which we put down to tiredness. His uncle had to be peeled off me and, seeing how upset I was, she would ring me at home and let me know how he was. He's fine now and has two degrees his name so it didn't put him off learning and he was always fine by the time I picked him up.

It is distressing but will probably turn out ok.
