Well, I am with Pooh and Piglet on this one.Torn. While I certainly don't belive in lying to your child, you might can get around this with wording." We are going to celebrate your birthday today!" I think however at 5, she might figure out when her birthday is and be quite confused by this. If she is in preschool, the class will do calander time each day. Every childs name will be on the calander on his or her date and the class makes a big deal of counting down the days untill each birthday.(I teach preschool).I am sure that by now she can also tell you her birthday. Such as my birthday is Dec.16th. As her birthday get nearer people who know her general time of birth ask her when her B.day is and she says Dec.16, someone might reply to her with an answer that will clue her into the fact that her birthday is after the trip. I am not sure of the answer, but I think pulling this off might be harder than you think.Five year olds are smart!
No matter what you tell her, be sure to celebrate her b.day at WDW.Get a PS for her favorite character's meals and spoil her like crazy that day. You will know what feels right to you.
