Sue, thank you for that suggestion. I have never tried that area near the CP, but we will certainly be trying that this year.
Michelle, we found that it was not the wait that was difficult for DD as you can generally have one person hold the space for the child, especially if you are willing to leave her stroller. Most families with small children are doing the same thing as none of the children seem to be able to wait in one place for that length of time.
The problem we have faced is the sound. Spectro is a very loud parade and DD does not typically have auditory sensory issues. The first time we watched Spectro, she got very excited as she could see it coming down the street, laughing and flapping her hands. However, as it got closer and louder, she covered her ears and began to scream. We saw three minutes that first year. The second year I went with ear muffs (she won't wear ear plugs) and placed my hands over her ears. She still did not stay for the entire parade.
I certainly don't want to discourage you from taking your DD to Spectro, it is truly wonderful. As a matter of fact, I keep trying each year to make it workable for my DD. I just wanted you to know.
