Use these tips to make New Years eve more enjoyable for you and your child:

Arrive before the other guests to allow for gradual accomodation of sounds and sights.

Find a quiet spot where your child can retreat in a noisy environment (e.g. pillow and blanket or sleeping bag under a table or in a separate room)

Provide your child with safe calming hand fidgets.

Chewy tubes and munchies may also be calming.

Offer noise cancelling ear plugs or headphones for the count down.
