My three year old is generally confident, noisy, energetic and happy. He absolutely loves nursery and loves nothing more than running around with other children of the same age. But he's petrified of birthday parties, unfamiliar noises, crowds, bouncy castles, large Christmas characters in displays, glittering Christmas trees, soft play areas... I've bought ear defenders ready to try to tackle the noise issue, but the visuals side is frustrating because it's difficult to avoid these things when out and about. Any suggestions?
