I can only suggest that you take her to the park and allow her the freedom to play on the apparatus without pressure so that she can begin to develop her own level of confidence, gradually this will build and she may eventually feel able to go on a slide and enjoy other activities. She is only 5 and I would not be too concerned yet, but she needs to have some space to explore her limitations by herself. She may yet grow up to be a sky diver or a bungee jumper and you may end up eating your words yet!!! Good luck.
