I pre warned for a week. I didn't hapr on about it, I just gave DS the facts. I told him it was called an immunisation and it was to stop him getting really really sick and having to go to hospital.

I told him there was a little needle and it would go into his arm and it might hurt for a second, but then it wouldn't hurt at all after that.

He was really great. No tears, no noise. He watched it and it didn't bother him.

Good luck!!
