This was a concert for the preschool crowd. Seeing the Wiggles perform live was a birthday present for my just-turned-3 year old and he was a little intimidated by the stage, noise and crowd. As soon as he heard familiar songs, he was much happier and even got a high five from his favorite Wiggle! Floor seats are the way to go: they encourage dancing and audience participation and the cast mingles with the crowd. The Wiggles are incredibly energetic and do their own stunts. Jeff, the Purple Wiggle, announced he is 57 years old then did flips!
The ushers allowed families to go in & out as needed and they were very understanding about the needs of toddlers. We got encouragement and special attention when my son balked at sitting in the dark, he wanted to go to the lobby and look at toys (for sale) and the TV screen showing what was on stage. They helped him adjust to the theater and once he was comfortable he had a great time- he didn't want to leave! The Wiggles warned parents that the theater seats sometimes fold up on small children and warned when they were going to do an especially dark musical number (Twinkle Twinkle with stars projected all around) which helped us prepare. The sound was good, louder than my kids are used to but not too loud. There were some gymnastics on the stage for the circus and a couple of songs we didn't know but mostly it was the familiar Wiggles performances & characters we know from the TV show and DVDs.
Worth every penny, glad we went.
