1) Costume Concerns: Let your child get used to the costume. You can practice having your child wear parts of the costume for short periods of time. If your child wants to wear the costume a lot in the days leading up to Halloween, go ahead and let them! The more comfortable your child is with the costume, the more likely she is to wear it on the big night.
2) Trick or Treat!: Practicing 'Trick or Treating' using your own house a few days before Halloween can help your little one to get the concept and be more relaxed about it. You can even take turns to model how to say 'Trick or Treat' and 'Thank you!'. Your child can also practice opening the door & giving out the candy!
3) Vocalizing or articulation issues? : If your child is not verbal or is difficult to understand, you can get creative about how he can participate in the Trick or Treating tradition. He could show a note-card that says 'Trick or Treat' on one side & 'Thank you' on the other or you could record the words on a small voice recorder that could be attached to her costume & she just needs to push the button.
With a little preparation and if they want to, all kiddos can participate in the Halloween tradition! Please feel free to contact me with any specific questions about how to prepare your child for Halloween and I can provide more strategies for your situation.
Happy Halloween, everyone
