Probably, many will try to argue with me and say that children of this age love life-size dolls. After all, they are often ordered for birthdays. This is understandable, but only is mum is around. In kindergarten everything is different. Thus, the kids behave differently.
Be very careful that you don't look frightening. You do not need to paint your face too much, or wear weird clothes. Do not forget that you have little kids in front of you. For the older group the costume of the Hatter is Ok, but for the youngest it is scary. Therefore, pay attention to your
appearance, do not scare the kids.
